All Drug Arrests by State in 2010

This map shows the drug arrest rates in the US in 2010 by state. The states are colored according the to the difference of arrest rates between blacks and whites per 1,000 people.

States colors get darker to show an increase in the chance that a black person will be arrested as opposed to a white person. See the map in full size here.

Some notes on the data:
Florida does not participate in the data collection program so there is no data for that state.
Illinois figures are partially estimated because of low reporting in some areas.

Arrest data comes from the Uniform Crime Reporting Program Data: Arrests by Age, Sex, and Race,
