Chicago's Rising Costs of Incarceration

This year Illinois will spend 1.4 billion dollars on the Department of Corrections. A large proportion of that money will be spent on locking up Chicagoans from the low-income neighborhoods on the west and south sides of the city.

Chicago's Million Dollar Blocks maps how much money is being spent on incarcerating individuals from each Chicago block. A large number of these blocks in the west and south sides of the city are costing the city over a million dollars. The data is based on sentence lengths and on an estimation that the Department of Corrections spends approximately $22,000 per year for each inmate.

The map includes two main layers: All Offences & Drug-Related. If you mouse-over a block on the map you can view the cost to the state of both drug-related incarcerations and for all offences. If you zoom out on the map you can also view a choropleth layer showing the cost of incarceration at the neighborhood level.
