Detaining tens of thousands of immigrants each day in the United States has been good for the bottom line of two private prison operators: Corrections Corporation of America (CCA) and GEO Group.

The two companies are responsible for imprisoning the majority of the 34,000 immigrants who must be locked up daily, per a federal quota established by Congress five years ago. CCA and GEO operate eight of the 10 largest immigrant detention centers and 72% of the privately contracted federal immigrant detention beds, according to a report from Grassroots Leadership.

Since lawmakers established the immigrant detention quota in 2010, CCA and GEO together expanded their share of the total immigrant detention system from 37% in the first year to 45% in 2014. GEO Group, alone, increased its share of the total immigrant detention system from 15% in 2010 to 25% in 2014.

This expanded share resulted in more profits overall for both companies. CCA’s profits went from $133 million in 2007 to $195 million last year. GEO’s profit total jump was even greater, from $41.8 million eight years ago to $143.8 million in 2014—a 244% increase, the report said.
