From remediating blight to optimizing restaurant inspections and pest control, cities across the country are using analytics to help improve municipal policy and performance. The continued adoption of analytics in city governments shows no sign of slowing, and as even more sophisticated tools such as machine learning and artificial intelligence are deployed, there is a critical need for research on how these practices are reshaping urban policy. By examining and capturing lessons learned from city-level analytics projects, practitioners and theorists alike can better understand how data- and tech-enabled innovations are affecting municipal governance. This report seeks to contribute to that developing field.
Members of the Civic Analytics Network, a peer group of leading urban chief data officers convened by the Harvard Ash Center, are using data-smart policymaking practices to develop, iterate, and replicate municipal analytics projects. The Civic Analytics Network was established as a community of practice in 2016 to support the growth and replication of analytics capacities in cities across the United States. Civic Analytics Network members represent many early leaders in urban analytics, and their cities’ analytics projects, policies, and approaches are at the forefront of this space. To help other cities learn how to use analytics to better serve their communities, this report profiles a selection of Civic Analytics Network city initiatives in areas ranging from municipal public safety and public health to housing and transportation.
A key component in creating, launching, and implementing an analytics project is adopting a systemic approach to project development. Whether a city has an established chief data officer position, an analytics team, or is a newcomer to public-sector data analytics altogether, there are various approaches and processes that can help initiate, scope, and implement a successful analytics project.
While many urban analytics projects have been largely successful in fulfilling their initial objectives and supporting better governance, most underwent multiple iterations. Furthermore, the continued expansion of data use in city government raises complex ethical questions that go to the core of American democracy. While more and more sophisticated technologies are being deployed to help improve government’s ability to serve the public, those new tools may be operating on assumptions or biases that will exacerbate, not ameliorate the challenges facing our most vulnerable populations. To successfully navigate this dynamic and rapidly evolving intersection of public policy and technology, government, at all levels, desperately needs better information on the state and implications of these new practices to help practitioners and academics alike find sustainable, equitable solutions.
To help capture lessons learned from both the technical and human side of city analytics, this report proceeds by: (1) introducing a five-step approach for developing an analytics project; (2) cataloging ten examples of Civic Analytics Network city analytics projects in the domains of public safety, housing, public health, and transportation; and (3) concluding with six policy recommendations for how other cities can implement analytics.

If a department, agency, or city is considering using analytics, there are a few ways to get started. While some organizations follow general standards of practice to provide a step-by-step guide on the key phases of project development, others follow a technical framework to identify the degree to which organizational and/or data resources will support a given project. Drawing on the various approaches, process guides, and methodologies developed by Civic Analytics Network cities and partners, this report highlights five key steps that cities can replicate to develop their own analytics projects: (1) identify the problem; (2) assess data readiness; (3) scope the project; (4) pilot the project; and (5) implement and scale the model.
The first step the Civic Analytics Network recommends—before considering what data an organization has available—is establishing a clear understanding of the problem to be addressed by a given analytics project. Determining data readiness or maturity is critical, but before an analytics project can even be scoped, it is important to ensure that the project’s objective is core to the performance or needs of the implementing organization; data-driven policymaking is not data use for the sake of data use. After working with departments to identify a mission-critical problem, analytics experts or data scientists can proceed with identifying data readiness, scoping and piloting the project, and so on.
From forecasting future needs to overcoming staffing or resource shortages, to condensing vast and disparate information into actionable insights, analytics can be a powerful tool in improving city governance, but it is most effective when used to enhance and support the efforts and priorities of city personnel. There is no better way to ensure that than by positioning data scientists within government to work with departments on tackling key issues collaboratively. It is important to note that many analytics teams are small, nascent offices with restrictive funding resources for data experts to introduce the value of data analytics to their cities’ bureaucracy; many new analytics teams or hires are established thanks to the support of the bully pulpit, and the mayor can play an important role in prioritizing data use to address policy needs in local communities.
Identifying a critical problem that can be supported or alleviated by analytics is challenging, but it is an important first step in structuring a successful analytics project. While data may abound, matching an area of need with the right data resources within an organization is vital. Developing an analytics project typically places data scientists in an internal consultant role; by working with a department or agency to identify their key issues or problems, data scientists can support mission-critical needs. For example, the City of Chicago’s Applied Analytics Guide prioritizes working in partnership with departments and agencies across government as part of its ten-step process to develop advanced predictive analytics projects. Chicago was an early leader in city-level data-driven policy as one of the first cities to create a chief data officer (CDO) position, which is housed within the city’s Department of Innovation and Technology (DoIT).
In Chicago, direct engagement with departments across city government helped DoIT build relationships that created an environment in which department leaders see the DoIT team as a resource to help them explore new solutions to key problems. DoIT does not prescribe data solutions, but rather supports the priorities of department leaders to optimize performance and/or service delivery in areas that the leaders identify as areas of need. Sometimes, however, public exposure of an underperforming service area can spur an analytics “intervention.” For example, following media coverage on restaurant inspections, DoIT helped craft an analytics model to help optimize restaurant inspections (see “Public Health” below).
Other cities similarly prioritize this problem identification phase as a way of developing meaningful partnerships with government agencies. Many Civic Analytics Network analytics teams are situated in their respective city governments as discrete groups tasked with supporting and collaborating with other departments or agencies by bringing data-driven insights and expertise to bear on key issues or areas of need.
Determining data readiness is a key facet of Civic Analytics Network cities’ approaches to analytics and a critical precondition to scoping any project. The success of an analytics project depends not only upon whether there is a need for data analytics, but also, and more importantly, on having the right personnel, data collection and storage practices, and stakeholder buy-in within and outside of the department or agency.
The University of Chicago’s Center for Data Science and Public Policy (DSaPP), a Civic Analytics Network partner, created a “Data Maturity Framework” to help prepare prospective project leaders for the development process. The framework provides an effective structure to help determine data readiness for an organization considering a new analytics project. Drawing on its team’s experience sourcing project proposals, DSaPP observed a trend: most prospective project managers referred to a desire to make use of tons of unused data. While having ready-made or already assembled data is a good start for any analytics project, DSaPP needed to help project managers understand that successful analytics projects begin with the identification not of unused data, but of critical issues in need of data-driven solutions. Once that issue area or policy need was identified, then data scientists could help project managers assess data readiness and begin structuring and scoping an analytics model.
DSaPP’s Data Maturity Framework consists of a questionnaire and scorecards to identify the technology, data, and organizational readiness within a department. The framework consists of a questionnaire and survey to assess readiness and three scorecard matrices on: (1) problem definition, (2) data and technology readiness, and (3) organizational readiness. Each scorecard helps organizations identify where they fall on a spectrum of four categories ranging from leading to lagging in terms of data readiness. Scorecard categories include: how data is stored; what is collected; privacy and documentation practices; personnel; data use policy; and buy-in from staff, data collectors, leadership, intervener, and funder. (See Appendix A, “The University of Chicago’s Data Maturity Framework”)
Assessing data maturity can also be approached from the macro level—for a mayor or chief data officer to assess the enterprise-wide maturity of municipal data, it is important to consider broad-scale questions such as how a government consumes data and how leadership uses data to make policy decisions. Determining the data maturity of city-wide practices is challenging, but cities across the Civic Analytics Network are leading by example through data-driven governance.
Once a department’s data readiness is assessed, it is time to scope the project. There is no one “right” approach to project scoping: in New Orleans, the city’s performance and data expertise team developed a project criteria framework to help scope projects; in the City of Chicago DoIT prioritizes prospective projects by using a framework of research question evaluation criteria. DSaPP’s Data Science Project Scoping Guide has been a particularly successful model for approaching project development and was featured as a pre-conference workshop at the Ash Center’s Inaugural Summit on Data-Smart Government in November, 2017.
DSaPP’s Data Science Project Scoping Guide was developed for prospective “Data for Social Good” fellowship projects (a program that supports aspiring data scientists by connecting them with real-world problems) in order to facilitate a continuous pool of well-developed projects that could be successfully deployed within DSaPP’s program cycle. Because each project needs to be scoped thoroughly enough for a data-use agreement, the project scoping steps help expedite project development by providing a concise framework for prospective projects. This project scoping approach helps managers focus on understanding what data is available, who the key stakeholders are for providing and using that data, and how that data is being considered to provide insights into a city governance problem. DSaPP’s four steps for project scoping are:
(See Appendix B, “The University of Chicago’s Data Science Project Scoping Worksheet”)
Chicago uses the Research Question Evaluation Criteria for scoping its predictive analytics projects and determining which projects are best suited for development. Similar to DSaPP’s project scoping steps, Chicago’s evaluation criteria guides project managers through key issues to better situate a prospective analytics project for success. (See Appendix C, “City of Chicago’s Research Question Evaluation Criteria”)
Piloting an analytics project is “the stuff of innovation.” This is where the trial and error of testing a new project happens. No matter how well prepared an analytics team is, sometimes—whether the problem lies in a key variable, an assumption built into the algorithm, or the project’s general approach—the pilot just does not perform as expected. While information on how best to pilot a municipal analytics project is limited, the frameworks, criteria, and guidelines developed by Civic Analytics Network cities and partners can serve as helpful resources and provide useful examples of how to approach and, ultimately, scale an analytics project.
Piloting an analytics project, like any effort to innovate in the public sector, is somewhat at odds with the bureaucratic preference for consistency and risk avoidance, but it is a critical phase that can yield important insights for improving performance when it is time for implementation on a larger scale. Moreover, starting with small-scale pilots can help limit risk and demonstrate clear results.
In an assessment of its pilot practices, the UK Government notes that “Once embarked upon, a pilot must be allowed to run its course. Notwithstanding the familiar pressures of government timetables, the full benefits of a policy pilot will not be realized if the policy is rolled out before the results of the pilot have been absorbed and acted upon.” The report goes on to argue that “pilots should be regarded less as ad hoc evaluations than as early stages in a continuing process of accumulating policy-relevant evidence.”
Piloting also allows for much needed course corrections to help better transition efforts in project-scoping to implementation; adjusting project parameters during the pilot phase can increase the likelihood of success at implementation and beyond.
Research and literature on implementing and scaling analytics projects remain limited, and given the variability of structures, budgets, and objectives for analytics projects, identifying generalizable practices for scaling these projects is challenging. The Ash Center’s Data-Smart City Solutions and the Civic Analytics Network have begun to capture early lessons from city-level analytics projects, and as more data-driven decision-making projects mature and are replicated, insights into how to improve and scale these leading projects will grow.
Currently, Civic Analytics Network cities are working to replicate models implemented by other member cities, and while some of those leading examples are highlighted in this report, further research and use cases on those replicated projects are forthcoming.
A city’s public safety capabilities encompass a wide variety of departments and agencies working to maintain the security and welfare of residents. Public safety means more than just having a police department; it is a cross-cutting issue in government, comprising a wide range of services that help prevent and manage crime, coordinate emergency preparedness, secure public transportation systems, and beyond. While the typical resident will likely only engage with their city’s public safety resources, such as the police or fire department, during an emergency, preventative practices, improved internal management, and tech-enabled policies implemented within and by the many departments that comprise a city’s public safety capacities can make the difference between life and death during those times of crisis. In the two examples below, data-driven efforts to strategically distribute smoke detectors and bolster early intervention systems that help supervisors in police departments identify officers in need of training or other mediation offer insights into how Civic Analytics Network cities and partners use analytics to support and improve the efforts of first responders across the country.
New Orleans’ Analytics Model Supports Smoke Detector Distribution and National Replication
According to the U.S. Fire Administration, three out of five home fire deaths happen in homes without smoke alarms, and the risk of death from fire in a home is cut in half when a home has smoke alarms. The New Orleans Fire Department (NOFD) provides citizens with free smoke alarms to help bring these life-saving devices to homes in need across the city, but NOFD Superintendent Tim McConnell wanted his department to be more proactive in improving the safety of New Orleans. —
NOFD partnered with the Office of Performance and Accountability (OPA), the city’s data team, to use a predictive analytics model to determine which houses in the city are least likely to have a smoke alarm and at the highest risk of fire fatalities. New Orleans did not have historical data on smoke alarm locations, and culling permitting records yielded limited results. The project had a breakthrough when an OPA team member turned to the U.S. Census Bureau’s American Housing Survey, which includes a question about smoke alarms. When OPA coupled this data with American Community Survey data, the team was able to identify key variables to help predict if a home is missing a smoke alarm and is at high risk for a fire-related fatality. The analytics model developed by OPA has helped NOFD identify on a block-by-block level where to target free smoke detector outreach and distribution efforts. From the project’s start in 2014 to 2016, NOFD was able to distribute and install 8,000 smoke detectors.
New Orleans worked with Enigma, a data analytics startup, to develop the methodology. Since the New Orleans model is based primarily on federal data, Enigma was able to partner with the American Red Cross and DataKind to replicate it across the nation.
New Early Intervention Systems Help Police Departments Better Manage Officer Performance
The University of Chicago’s Center for Data Science and Public Policy (DSaPP) has partnered with Civic Analytics Network cities and others to build and deploy the first data-driven early intervention systems (EISs) for police officers. EISs enable departments to provide training, counseling, and other interventions for officers who are identified as likely to have an adverse incident. Adverse incidents include complaints from a citizen or colleague, use of force or other tactics, or accident or injury. Early EISs only tracked a handful of simple indicators, such as the number of times an officer used force, and omitted context. For instance, the officer’s assigned beat was typically not logged in the system, meaning there was no way to see in the EIS if an adverse incident such as use of force occurred within or beyond the officer’s beat.
DSaPP’s system uses analytics to find predictors of adverse incidents in the department’s data by, for example, tracking which officers respond to the highest number of suicide calls. This allows administrators to assess whether additional training or counselling is needed. DSaPP’s EIS model adapts over time and automatically learns from how supervisors interact with, use, or deprioritize the system’s findings. DSaPP has deployed the system in Charlotte-Mecklenburg and Metropolitan Nashville and, as of spring 2018, is working with two Civic Analytics Network cities to build prototypes.
During the development of the Nashville model, the University of Chicago’s DSaPP team determined that of the approximately 1,000 officers in the city’s department, around five percent have an adverse incident each year. Typical or traditional EISs use a threshold-based model to identify officers in need of intervention, and while that system captures 80 percent of the officers who will have an adverse incident, it does so by flagging almost two thirds of police. A system that recommends that a department retrain two thirds of the police force is simply not a useful administrative tool, and while it can reasonably be argued that the more training a department receives the better, given the already limited resources of many police departments offering universal, continuous training is infeasible. So, given those limitations, the University of Chicago worked to create a more sophisticated system that includes more data, context, and other factors to streamline the EIS results helping department administrators be better equipped to manage their personnel.
The new EIS designed by the DSaPP team still flagged 80 percent of the officers who will have an adverse incident, but targeted only 30 percent of the department for intervention. Additionally, the new EIS assigns a risk score based on past performance, providing an additional level of detail to help supervisors gauge whether an officer needs an intervention. The risk score and EIS are decision-support tools; neither tool replaces the supervisor’s role in forming judgments about officer training needs and performance. Data collection on how this new system has helped reduce adverse incidences is ongoing.
Based on learning over the course of this project, DSaPP has published a few rules of thumb for EISs: (1) provide the department with a system that does not create an unmanageable administrative burden; (2) help the department assign a technical lead within the department to be responsible for the EIS; (3) make the system easy to use; (4) value police supervisors’ expertise and input in the EIS design; and (5) clearly communicate the objective and scope of the EIS project.

Cities face an increasing need for housing as more and more of the U.S. population moves into urban areas. Providing safe, secure, affordable, and equitably available housing is key to the future stability and success of cities. To this end, Civic Analytics Network cities are using data-driven insights to improve housing conditions in their communities with projects focused on improving housing inspection performance, minimizing overlooked health and safety risks, and remediating blight outbreaks.
San José Uses Analytics to Help Housing Inspectors Keep Residents Safe
San José’s Multiple Housing team in the city’s Code Enforcement Office is tasked with monitoring all properties with three or more units, which totals more than 4,500 properties in the city. It is impossible for the Multiple Housing team to inspect every property each year, so the city partnered with the DSaPP through the Civic Analytics Network to help the inspectors identify properties that are at the highest risk for violations. DSaPP developed a predictive model to provide a view of property violations over time, drawing upon construction permit records and other indicators to develop a model that identifies possible higher-risk properties in the community. The model was developed in close collaboration with the inspectors in San José; DSaPP worked with inspectors, interviewed them, and joined them on inspections to observe how they prioritize and gather information during a site visit. The analytics model DSaPP developed prioritizes violations that pose greater health and safety risks, such as exposed wiring or fire hazards. DSaPP identified four factors that were particularly predictive of higher-risk conditions: (1) amount of time since last inspection; (2) previous health and safety violations; (3) lack of recent building permits; and (4) violation rates of nearby properties. Field tests for this model concluded in late 2017.
Analytics Model Focuses on Eliminating Income Discrimination for Prospective Tenants in New York City
In New York City, Title 8 of the Administrative Code of the City of New York prohibits discrimination based on a number of factors, including race, gender, and religion. The law also includes provisions to protect individuals who receive public assistance from being discriminated against based on their source of income. Despite this, however, income-based discrimination is among the top housing-related complaints in the city.
To curb discrimination against prospective tenants, including tenant harassment, source-of-income discrimination, and illegal conversions of apartments, the Commission on Human Rights partnered with the New York City Mayor’s Office of Data Analytics (MODA) to build a model to help prioritize investigative resources. MODA wanted to identify areas in which landlords were most likely to turn away prospective tenants with housing vouchers—not only to prosecute proven violators, but also to send a clear message that violations of this nature would not go unnoticed and to discourage landlords across the city from discriminating in the first place.
With this in mind, MODA set out to identify the landlords engaging in discriminatory behavior focusing particularly on identifying and punishing larger property management firms. By focusing on identifying the largest landlords making these violations, the city hoped that as a consequence smaller potential offenders would remediate their behavior. MODA’s model has helped the city better identify illegal housing practices, and while the Commission investigates all allegations of income discrimination, MODA’s efforts have helped the Commission better manage their inquiries and, ultimately, improved the city’s ability to curb future incidents of discrimination.
New Orleans Uses Data-Driven Insights to Reduce Blight
After Hurricane Katrina in 2005, rebuilding New Orleans was a daunting, arduous endeavor, and many areas that were damaged by the wind and flooding were left untouched in that state for years. As a result, rampant blight took hold in and around those damaged properties across the city. When Mayor Mitch Landrieu took office in 2010, blight remediation was a top priority, and the Office of Performance and Accountability (OPA), the analytics hub of New Orleans’ city government, was tasked with developing analytics and performance management tools to help tackle this dangerous housing issue.
OPA developed BlightSTAT as a performance management tool to improve services and results through the use of data. OPA also created a Blight Scorecard to address a backlog of more than 1,500 properties awaiting a decision by the Department of Code Enforcement. The Blight Scorecard allows mid-level supervisors to score a property on several dimensions and then receive a weighted recommendation between 0 and 100, 0 meaning the property should be demolished and 100 meaning it should be sold. Those mid-level supervisors and their superiors can use the tool to evaluate properties, vastly increasing the speed and consistency of the process at various levels in the department. Like Chicago Police’s EIS, the scorecard is a decision-support tool and does not replace human judgment—it provides a recommendation, and the director reviews the available information and decides whether to approve each demolition.
This new tool has improved the workflow of the city’s Code Enforcement Department by directing negative judgments to supervisors for review prior to escalating them to the attention of the director. Moreover, the new process adds efficiency by removing all paper components. Use of this tool effectively eliminated the backlog of blighted properties in the city. Other cities are also tackling blight remediation with analytics; for example, Cincinnati partnered with the University of Chicago’s DSaPP via the Civic Analytics Network to develop an early detection model.
From the risk of foodborne illness to viral outbreaks, mitigating public health concerns is a matter of good, forward-looking governance. The global health risk posed by mosquito-borne viruses like Zika and West Nile is immense, and as the impact of climate change becomes more overt the risk of such viral outbreaks will only grow. Forecasted population and environmental changes pose unprecedented challenges for local governments, but analytics can provide critical insights to help cities prepare for and curb the impact of future outbreaks.
Monitoring food quality and safety in a city are similarly challenging tasks, due to the complexity of regulations for food preparation, storage, service, and so on. Cities across the Civic Analytics Network have developed analytics models to help city officials deploy their limited resources more effectively to monitor and manage restaurant inspections and pest control. By forecasting areas at risk for mosquito-borne disease, rodent infestation, and poor food quality, cities are able to better manage their limited resources and provide their communities with a safer, healthier quality of life.
Chicago Uses Analytics to Prepare for Forecasted Spike in West Nile Virus
By the end of this century, Chicago’s climate is projected to become so warm that it will mirror the conditions seen in present-day Alabama. As warmer climates shift northward and expand mosquito-friendly environmental conditions, the risk of mosquito-borne viruses will increase considerably. The forecasted spike in mosquito population in the Chicago area helped prompt Chicago’s Department of Innovation and Technology (DoIT) to partner with the Chicago Department of Public Health (CDPH) to use data to find new solutions for this projected public health issue. The city built a predictive model to determine one week in advance whether or not a particular area will have West Nile virus-carrying mosquitoes. With such a model, Chicago can direct mosquito-spraying efforts towards areas that pose the greatest risk, mitigating the potential of a viral outbreak.
The concept for Chicago’s West Nile virus analytics project came via Kaggle, an online platform for analytics and predictive modeling competitions. In early 2015, CDPH, in partnership with DoIT, launched a Kaggle competition of its own by posting some West Nile virus visualizations and starter code in R (a program language and software for running statistical analyses) and Python (a high-level programming language for general computer program and analyses) on Kaggle Scripts. In 2017, following a successful pilot program, Chicago operationalized its West Nile virus analytics model. Chicago’s efforts to combat West Nile virus can potentially be replicated to help cities manage public health risks associated with other mosquito-borne illnesses, including the Zika virus. Chicago’s model along with instructions for running it are available on the city’s GitHub page.
Zika Outbreak Triggers Coordinated Analytics Response from Cities across the U.S.
The Zika virus burst onto the international stage in 2016 as a global health emergency. While Zika is not a new virus, the unprecedented outbreak in 2016 brought this disease to the fore of public health debates around the globe. While travel-related Zika cases in the United States remain limited, local health officials and urban policymakers alike must grapple with the risk that Zika-infected mosquitoes pose to their communities. Zika is transmitted by the Aedes aegypti mosquito, which thrives in warm, wet climates. So, like West Nile virus, the risk of Zika in cities across the country will likely only grow in the years to come as climates become warmer around the globe.
Unlike Chicago’s forecasted West Nile virus risk, New Orleans is already home to abundant Aedes aegypti populations. New Orleans, like most cities, has well-established mosquito monitoring systems in place, but following the 2016 Zika outbreak additional methodologies and resources for controlling, monitoring, and predicting population spikes were needed. For example, New Orleans is using ArcGIS (a geographic information system, GIS, software system) to create risk maps based on analytics to help identify baseline larval habitats and to streamline sampling after the city intervenes with a population.
National analytics strategies for addressing the risk of the Zika virus are still being structured, but a key first step for successfully deploying analytics in this area is to identify risk factors that could potentially exacerbate climate-based and warm season outbreaks. For example, in his Data-Smart City Solutions article, Jonathan Jay argues that analytics that correlate mosquito populations with vacant property areas can help cities pinpoint areas at high risk for an outbreak. Integrating or replicating existing analytics models is a likely next step. For instance, New Orleans is already using analytics to tackle blight, and linking this housing-specific effort to public health data could provide invaluable insights into mosquito-borne disease outbreaks and how to curb them.
Chicago Optimizes Restaurant Inspections with Analytics
Chicago has more than 7,300 restaurants within city limits, plus thousands of grocery stores and other food vendors. Despite the fact that the number of food establishments in Chicago totals more than 15,000, however, the city only employs three dozen inspectors. With no additional resources available for restaurant inspectors, the city needed to work smarter to improve its inspection performance. Following media reports highlighting poor food quality and inspection performance in restaurants, city officials focused on finding new solutions to help improve inspection processes. Chicago’s Department of Innovation and Technology (DoIT) worked with the Chicago Department of Public Health (CDPH) to develop an analytics model that would help forecast restaurants’ risk of failing inspection. The model, developed in partnership with AllState’s pro bono team, enabled the city to identify critical violations an average of seven days earlier than the previous process for ordering the inspections. In addition, Chicago’s Data Portal (the city’s open data hub) houses a Food Inspections tracker to provide the community with transparent, real-time information on the food inspection results for city restaurants.
Chicago’s DoIT Team Fills Information Gap with 311 Data to Curb Rodent Infestations
The City of Chicago’s Department of Innovation and Technology (DoIT), in partnership with Carnegie Mellon University’s Event and Pattern Detection Laboratory, developed predictive analytics tools to support efforts to combat rodent infestations in Chicago and to help the city develop more effective rodent baiting programs. Because the city had limited formal information documenting rodent populations, geography, and other factors critical to helping city officials tackle infestations, DoIT utilized 311 data in its analytics model to fill the information gap.
311 call data is the foundation of the city’s rodent infestation analytics model and helps the city determine where rodent infestations could exist and predict where those populations could spike. Geospatial representations of this information support the Department of Streets and Sanitation’s rodent baiting program. Sean Thornton, a program advisor for the Civic Analytics Network based in Chicago, notes, “In July 2013, Mayor Rahm Emanuel announced that as a result of the City’s increase in preventive rodent baiting efforts in 2012, resident requests for rodent control services have dropped 15% in 2013.”
Washington, D.C., Uses 311 Data and Analytics to Support Rat Abatement
Following a surge in 311 calls related to rodent sightings in 2016, the District of Columbia’s city government decided to use analytics to help combat the city’s rat problem. The Lab @ DC, situated in the Office of the City Administrator, and the Office of the Chief Technology Officer (OCTO) work together on various city priorities and projects to develop data-driven solutions to help city government better serve the District. As part of this broader effort, the Lab @ DC and OCTO data scientists partnered with the rodent control team at the Department of Public Health to develop an analytics model to identify environmental variables that help predict where a rat infestation is likely to develop. To build an analytics model, the city is using 311 data, and, similar to rodent infestation management efforts in Chicago, D.C. is working to identify leading indicators within 311 data to support that model. The city’s efforts to develop an analytics model to support rat abatement are ongoing.
Rising urban populations and new technologies such as automated vehicles are pushing cities to rethink their transportation systems and regulations to ensure driver and pedestrian safety. New mobile applications, technologies, and modes of transit are revolutionizing how residents traverse their home cities, and it is increasingly apparent that existing city resources and regulations are insufficient to deal with these new practices. Outdated public transit and transportation infrastructure is a common issue in cities across the U.S., and while a cross-cutting strategy with immense funding support is required to address this issue, data analytics can offer a cost-effective way forward for cities. Transportation and data analytics go hand and hand, and the wealth of data available in transportation is a critical and in many cases low-cost resource that can help city officials assess and improve transportation systems. Cities need to be equipped with the right personnel and tools to use analytics to understand and help regulate existing and new transportation modes and patterns.
In parallel to city efforts to understand the implications of new technologies and services in transportation, a global movement called Vision Zero is focused on eliminating traffic fatalities. As part of this movement, which originated in Sweden in 1997, cities across the Civic Analytics Network, from Boston to Los Angeles, are developing analytics models and visualization platforms to make progress toward this goal. How cities will grapple with the implications and challenges of automated vehicles along with the complexity of multi-modal, shared roads remains to be seen, but municipal analytics models that are being developed can help prepare cities for the changes brought by these and other new technologies.
New York City’s Analytics Team Aims for Zero Traffic Fatalities with Exposure Map
As part of the Vision Zero movement, New York City began developing an analytics model in 2015 with DataKind to enable city officials to assess whether a new transportation project is high risk (i.e., likely to result in injury or unsafe traffic circumstances) and to estimate the likelihood of various outcomes. For example, if the Department of Transportation (DOT) is developing a new intersection or traffic lane design, the analytics model assesses the risk of injury in that intersection or lane design, allowing project managers to adjust the design and recalculate to get the safest results while still accounting for need to improve traffic patterns and minimize delays.
While limited data rendered this initial project design unsuccessful, the model’s ability to calculate the number of cars on a road produced a useful exposure model that is being used by the city’s DOT to more accurately determine the effectiveness of different street designs. The exposure map allows the DOT to forecast the number of cars on the road to help better manage traffic patterns and improve road safety for pedestrians and drivers alike.
From improving public health outcomes to supporting safer transportation systems, analytics can offer new insights and improvements to city governance across core issue areas. While the structure, application, and processes used to develop, iterate, and implement the ten examples of Civic Analytics Network projects detailed in this report vary significantly, there are common policies adopted and operating within each that other cities can replicate. There is a need for more research and literature on city-level analytics to help practitioners and theorists alike understand how data-driven decision-making practices are operating within municipal governments. This report concludes with six policy recommendations derived from the Civic Analytics Network’s work in public health, transportation, housing, and public safety to help spur and guide the effective development of analytics projects in other cities across the U.S.
Adopting an open data policy can be a boon to rapidly, transparently, and collaboratively developing comprehensive analytics projects. Open data policies and portals enable city governments to operate with greater transparency to the public and to connect them directly to external researchers, algorithms, and/or datasets that can support more effective analytics project development. If advanced data use is a few steps down the road for a city, crafting an open data roadmap can help city government become more data-savvy to build towards future open data policy conversations. In early 2017, the Civic Analytics Network published an open letter to the open data community offering guidelines to help advance government capabilities for data portal development and to help deliver on the promise of transparent governance. In June 2018, Civic Analytics Network members reaffirmed their commitment to those eight guidelines, publishing a one-year later letter to the open data community.
By creating job descriptions and new frameworks for programs to appeal to data scientists considering positions outside of government, cities can attract dynamic, data-literate personnel to embed and distribute data skills at various levels within city government. Whether it is creating a CDO position, establishing an analytics team, or simply embedding a data scientist within a department, establishing a role for data expertise with the support of senior leadership can enable city officials to develop the analytics projects that they need most. In addition to bringing in data champions and expertise, cities can also improve internal capacities by designing training programs to provide critical professional development opportunities to city hall personnel. San Francisco’s SF Data Academy, which provides a pathway for city employees to receive continuous professional development focused on data skills and analytics from within government, is a leading example in city-level analytics training programs.
Developing an analytics project places data scientists in an internal consultant role, as they are typically situated outside of the department where that project will be implemented. It is important to establish pathways for data scientists to collaborate and receive input from the relevant department or agency, and, simultaneously, pathways to incentivize city personnel to engage with those new data science experts need to be established by supervisors or even from the bully pulpit. Government personnel operate in a bureaucracy and it is important for their supervisors to establish space in their day-to-day responsibilities to help them ‘make the time’ to engage on data-focused projects. By incentivizing department or agency personnel to connect with data scientists within city hall, supervisors or even the bully pulpit can open up space within city staff’s day-to-day schedule and performance requirements to enable them to pursue analytics solutions to core issues. Beyond connecting departmental personnel to data scientists via substantive pathways for collaboration, cross-departmental engagement is also key. While many city departments maintain useful data repositories, that data is often siloed or incompatibly structured, rendering analyses with data maintained by various departments infeasible. Establishing resources, tools, or policies to help streamline data standardization and warehousing can enable cross-departmental data sharing and is a critical facet of becoming a data-smart city. In Los Angeles, GeoHub, the city’s open data platform, offers unprecedented access to the city’s highly integrated data resources. GeoHub is a publicly available platform designed to allow the public to explore, visualize, and download location-based open data. It also allows departments across the city to share, access, and collaboratively utilize other departments’ data. Other Civic Analytics Network members are working to replicate this platform in their cities.
Whatever methods a city uses to encourage data analytics, adopting an effective project management process means establishing a policy framework that enables data science experts to design analytics projects with the support of the city’s legal, administrative, and oversight capacities. “Human-centered design” is a commonly used method among Civic Analytics Network cities and offers methods that help craft analytics projects that are responsive, equitable, transparent, and designed with community members in mind. To develop useful analytics projects, cities need enterprise-wide procedures, such as data usage practices, security protocols, or standardized legal and data sharing agreements. For example, in New York City, the Mayor’s Office of Data Analytics (MODA) created the MODA Process Map to help departments develop data use practices and internal awareness. While these procedures can help streamline, stabilize, and embed data use practices across government, project managers must be mindful of potential blind spots, such as algorithmic biases, that may be unwittingly built into their models. Allegheny County, Pennsylvania, a county-level member of the Civic Analytics Network and home to the City of Pittsburgh, a network member, has developed a Data Warehouse to create a more efficient and data-driven environment for the delivery of human services. The Data Warehouse has enabled county administrators to learn more about individual clients and address gaps in coverage. Many Civic Analytics Network cities are now pursuing their first data warehouses, and this network-wide trend represents an important shift in practice from project-based data-use efforts to organization-wide strategic data practices and policies.
Chief data officers may work within the walls of city hall, but they are members of a broader community and data ecosystem. The best analytics insights come when city government data use and civic engagement converge—after all, the public is the constituency for city analytics. Whether an organization is analyzing datasets available on an open data portal, developing a data visualization, or scoping a predictive analytics project, the results any of these efforts yield are better crafted when co-created with the public. By producing analytics models informed by direct input from city residents or developed in partnership with a civic tech group, cities will garner better service improvements and data-driven insights. Kansas City, MO, for example, uses a quarterly feedback mechanism called the Citizen Survey through which residents can both respond to prompt questions provided by the city and communicate their top priorities for the city. Citizen Survey is a leading example of a municipal citizen survey tool and has established a continuous feedback loop to link citizen perspectives to Kansas City’s performance and services.
Analytics is a practical tool for overcoming resource shortages and for distilling vast and disparate data, but it can also lead to the reproduction of biases and inequities under the banner of data science. Establishing standards of practice and mechanisms that ensure clear and continuous engagement with the public are critical components for cities to maintain transparent, equitable governance, and for incorporating inclusive analytics practices into city government. Under the leadership of San Francisco’s chief data officer and the new chair of the Civic Analytics Network, Joy Bonaguro, the network is developing a toolkit to help cities assess the risks and biases of algorithms. This toolkit focuses on algorithms developed both within city hall and by third-party vendors, and aims to help safeguard city analytics so that future data-driven efforts are able to produce fair and equitable solutions for the benefit of all community members.
