Since the passage of the Homeland Security Act of 2002, DHS, through the Office of Immigration Statistics (OIS) has:
- Collected and disseminated data and information useful in evaluating the social, economic, environmental, and demographic impact of immigration laws; and
- Established standards of reliability and validity for statistical immigration data collected by the Department’s operational Components.
As of September 2023, the Office of Homeland Security Statistics is responsible for collecting, disseminating, and establishing standards for immigration data.
Immigration data is collected and disseminated from numerous homeland security agencies, including U.S. Customs and Border Protection, U.S. Citizenship and Immigration Services (USCIS), and Immigration and Customs Enforcement (ICE) as well as the Department of Justice (DOJ) Executive Office for Immigration Review. The three homeland security operational Components oversee lawful immigration to the United States and safeguard the borders.
