"The few studies on the local economic impacts of prisons to date have not found significant positive impacts. For example, a study by the Sentencing Project challenges the notion that a new prison brings economic benefits to smaller communities. Using 25 years of data from New York State rural counties, the authors looked at employment rates and per capita income and found 'no significant difference or discernible pattern of economic trends' between counties that were home to a prison and counties that were not home to a prison (King, Mauer, and Huling 2003). According to a recent study by Iowa State University, many towns that made sizeable investments in prisons did not reap the economic gains that were predicted (Besser 2003). Another analysis in Texas found no impacts as measured by consumer spending in nearly three-fourths of the areas examined (Chuang 1998)."
