Immigration Data & Statistics
Since the passage of the Homeland Security Act of 2002, the Office of Immigration Statistics (OIS) has responsibility to carry out two statutory requirements: 1) to collect and disseminate to Congress and the public data and information useful in evaluating the social, economic, environmental, and demographic impact of immigration laws; and 2) to establish standards of reliability and validity for immigration statistics collected by the Department’s operational Components.
The following are key data sets and resources published by the Office of Immigration Statistics.

The following are key data sets and resources published by the Office of Immigration Statistics.
Yearbook of Immigration Statistics
The Yearbook of Immigration Statistics is a compendium of tables that provides data on foreign nationals who were granted lawful permanent residence, were admitted into the United States on a temporary basis, applied for asylum or refugee status, or were naturalized.
Lawful Permanent Residents
Lawful permanent residents (LPRs), also known as “green card” holders, are non-citizens who are lawfully authorized to live permanently within the United States.
Refugees & Asylees
A refugee is a person outside his or her country of nationality who is unable or unwilling to return to his or her country of nationality because of persecution or a well-founded fear of persecution. An asylee is a person who meets the definition of refugee and is already present in the United States or is seeking admission at a port of entry.
U.S. Naturalizations
Naturalization confers U.S. citizenship upon foreign nationals who have fulfilled the requirements Congress established in the Immigration and Nationality Act (INA).
U.S. Nonimmigrant Admissions
Nonimmigrants are foreign nationals granted temporary admission into the United States.
Immigration Enforcement Actions
DHS engages in immigration enforcement actions to prevent unlawful entry into the United States and to apprehend and repatriate aliens who have violated or failed to comply with U.S. immigration laws.
Data Visualization
Infographics produced by the Office of Immigration Statistics to make data provide by Department of Homeland Security components more readily available to the public.
Fact Sheets
Fact sheets on widely varying topics ranging from characteristics of those apprehended at the border in a given time period to reports on immigrants’ interstate migration between the acquisition of lawful permanent resident (LPR) status and citizenship.
Population Estimates
Population estimates for unauthorized immigrants, nonimmigrants, and lawful permanent residents.
Research Library
White papers and special projects related to immigration which may expand upon concepts in core reporting or topics of special interest to stakeholders.
