"Every dollar transferred to a 'prison community' is a dollar that is not given to the home community of a prisoner, which is often among the country's most disadvantaged urban areas. According to one account, Cook County Illinois will lose nearly $88 million in federal benefits over the next decade because residents were counted in the 2000 Census in their county of incarceration rather than their county of origin (Duggan 2000). Losing funds from the 'relocation' of prisoners is also an issue for New York City, as two-thirds of state prisoners are from the city, while 91 percent of prisoners are incarcerated in upstate counties (Wagner 2002a)."
