The Office of Homeland Security Statistics (OHSS) oversees the Department of Homeland Security’s (DHS) statistical reporting standards and ensures consistency in reporting to the public. To fulfill our responsibilities, OHSS reports and data must:
- Meet rigorous data quality standards, reflecting consistent reporting methodologies and definitions;
- Be credible and free from political influence;
- Be published on a regular and predictable schedule; and
- Be available in digital formats and released with the greatest possible granularity, consistent with appropriate privacy and law enforcement protections.
Report Publication Schedule
OHSS publishes regular reports and data on an annual, quarterly, or monthly basis. See our planned publications for Fiscal Year 2024.
New Report Prioritization
- Directed by statute or executive order
- Independent reporting directed by the Secretary (including DHS reports that are delegated to OHSS)
- Directed by the Office of Management and Budget
- In response to Government Accountability Office or Office of Inspector General recommendations
- To establish reporting presence in all DHS mission areas
- To increase data transparency in consultation with external stakeholders
The Foundations for Evidence-Based Policymaking Act of 2018 ("Evidence Act") requires that federal agencies appoint a Statistical Official, who directs and coordinates agency statistical policy and who works with the agency Chief Data Officer to establish agency data standards. OHSS is led by the DHS Statistical Official and supported by the DHS Statistical Official Council, which consists of senior career officials appointed as Statistical Officials for each operational Component that provides data to OHSS.
