FEMA operates under which department in the United States government?

FEMA, or the Federal Emergency Management Agency, operates under the Department of Homeland Security (DHS) in the United States government. The agency was established to coordinate the federal government's response to natural and man-made disasters, ensuring that resources are effectively managed during emergencies. The Department of Homeland Security, formed in response to the 9/11 attacks, is responsible for protecting the nation from various threats and hazards, which includes disaster management. FEMA’s mission closely aligns with the goals of the DHS, as it helps individuals and communities prepare for, respond to, recover from, and mitigate the impacts of disasters.

In contrast, the other departments mentioned do not have a direct role in emergency management. The Department of Defense focuses on military and defense matters, the Department of Health and Human Services addresses health-related issues and public health programs, and the Department of Education deals with educational policies and funding. Each of these agencies has important functions, but none are centered on emergency management as FEMA is within the DHS.
