> Nearly two-thirds of private prison contracts mandate that state and local governments maintain a certain occupancy rate – usually 90 percent – or require taxpayers to pay for empty beds. In Arizona, three private prisons are operating with a 100 percent occupancy guarantee, according to Mother Jones. There’s even a lockup quota at the federal level: The Immigration and Customs Enforcement’s detention budget includes a mandate from Congress that at least 34,000 immigrants remain detained on a daily basis, a quota that has steadily grown each year, even as the undocumented immigrant population in the United States has leveled off.
It's not so simple.
