Following deadly fires in illegally converted downtown New York City apartments, officials realized they had a problem. The Mayor's Office embarked on a mission to prevent fires and mitigate risk by using data the city was already sitting on.

In a cooperative effort between several city departments, officials now use analytics to prioritize decisions in a city where it's not practically possible to unturn every stone. The use of analytics resulted in a more than 500 percent increase in the number of buildings that were vacated after inspection, as this video explains.
