population crash
Sudden demographic collapse
A population crash is a rapid, dramatic decline in the number of individuals in a species or group.
The term appears in ecology to describe sudden collapses from disease, habitat loss, or resource depletion: The deer population crashed after the harsh winter.
It extends to human demographics and economics: Some countries face a population crash as birth rates plummet.
