Topics and Data

The Office of Homeland Security Statistics (OHSS) was established in September 2023, replacing the former Office of Immigration Statistics (OIS). OHSS was established to perform independent statistical reporting for the Department of Homeland Security (DHS). Prior to the creation of OHSS, DHS was the largest domestically-focused federal department without an independent statistical unit or agency mandated to share data with the public. OHSS makes objective, credible, accurate, relevant, and timely federal homeland security statistics available to the public, our interagency partners, and Congress — anyone interested in obtaining quality evidence related to DHS’s vital mission.

OHSS will continue to produce legacy OIS data and reports along with a number of new immigration products, and also report on a range of additional topics, including immigration, law enforcement use of force, and intellectual property rights enforcement. Over time, OHSS reports will cover all DHS homeland security statistical data, including cybersecurity; emergency management; infrastructure protection; maritime; screening; terrorism and targeted violence; and chemical, biological, radiological, and nuclear.
