population census
National nose count
A population census is an official count of all the people living in a country or region, typically conducted at regular intervals—every ten years in the United States.
Beyond raw numbers, censuses gather demographic data: age, sex, race, household composition, employment.
The results shape political representation, government funding, and policy decisions.
The census showed rural areas losing population to cities.
