This post was created thanks to London's Metropolitan Police, that published crime data for London's boroughs. Their data base consists even such details like number of stolen bicycles.Crime rates (Rates per thousand population) were calculated according to: (crime / the resident population)*1000. Many boroughs have very high daytime population, so the resident population is only a fraction of the daytime population and that makes the crime rate so high in some boroughs.Hope to see such data for other cities.
