Economic Incentive for Prison Construction
"The economic benefits of new prisons may come from the flow of additional state and federal dollars. In the decennial census, prisoners are counted where they are incarcerated, and many federal and state funding streams are tied to census population counts. According to the U.S. General Accounting Office (2003), the federal government distributes over $140 billion in grant money to state and local governments through formula-based grants. Formula grant money is in part based on census data and covers programs such as Medicaid, Foster Care, Adoption Assistance, and Social Services Block Grant (U.S. General Accounting Office 2003). Within a state, funding for community health services, road construction and repair, public housing, local law enforcement, and public libraries are all driven by population counts from the census."
