Differences
In British English, the more common modern term is 'Civil Protection' or 'Resilience', as the governmental department responsible is the Civil Contingencies Secretariat.

In American English, 'civil defense' remains the standard, umbrella term, often associated with FEMA (Federal Emergency Management Agency).

Frequency
The term is used more frequently in historical or policy contexts in the UK. In the US, it remains a standard term in official government communications and emergency management discourse.
