About Citizen Corps
We all have a role in hometown security.
Citizen Corps is FEMA’s grassroots strategy to bring together government and community leaders to involve citizens in all-hazards emergency preparedness and resilience.
Citizen Corps asks you to embrace the personal responsibility to be prepared; to get training in first aid and emergency skills; and to volunteer to support local emergency responders, disaster relief, and community safety.
There are currently 2,403 Councils which serve 225,985,904 people or 79% of the total U.S. population.
