Cos Cob crime rates are not available from the FBI crime report. The FBI's uniform crime reporting program (UCR), gathers data from more than 18,000 law enforcement agencies. The agencies include city, university, college, county, state, tribal and federal law enforcement agencies.

This does result in approximately 20 million people who live in areas where the FBI does not provide crime reports. These areas tend to be smaller towns, villages or suburbs. Given that Cos Cob crime stats are not covered by the FBI crime reports, either data from local enforcement agencies is applied or estimates are calculated based on demographic data including, but not limited to: home prices, income per capita, poverty rates, unemployment rates, educational achievement and population density. The Cos Cob crime estimates should be used at your own risk. Please be aware that the data displayed above is estimated and not officially reported by any agency.
