The United States has the largest immigration detention system in the world. In the 1980s, it held fewer than 5,000 people each day. By 2024, that number was 39,000, and today it is increasing sharply again. While Republicans are often the loudest voices against immigration, the detention system expands no matter which party is in power.

Immigration Detention Inc. is a damning investigation of the ways immigration detention generates income while those imprisoned are starved, sickened, and exploited on a daily basis. Drawing on over a decade of research and focusing on detention centers in New Jersey and New York, Nancy Hiemstra and Deirdre Conlon follow the money to map public and private financial relationships and trace how detention contracts for food, medical care, and in-facility stores are fought over to the penny. By breaking down how immigration detention works, they reveal a profit-driven system that harms and corrupts communities across the U.S. At a decisive moment in history, the call is clear: dismantle immigration detention systems everywhere.
