As cities also start to look back at historical data, fascinating discoveries are being made. Mike Flowers, the chief analytics officer in New York, says that if a property has a tax lien on it there is a ninefold increase in the chance of a catastrophic fire there. And businesses that have broken licensing rules are far more likely to be selling cigarettes smuggled into the city in order to avoid paying local taxes. Over in Chicago, the city knows with mathematical precision that when it gets calls complaining about rubbish bins in certain areas, a rat problem will follow a week later.
Is this sort of the direction you're going in?
