Congress created the Department of Homeland Security in 2002 by combining 22 agencies, which are responsible for a vast array of activities. The largest agencies are Customs and Border Protection, the Coast Guard, the Federal Emergency Management Agency, Immigration and Customs Enforcement, the Transportation Security Administration, Citizenship and Immigration Services, and the Secret Service.
The department will spend $62 billion in 2019, or $490 for every U.S. household. After adjusting for inflation, spending has increased 340 percent since 2000. It employs 184,000 people.
