Facts by Decade

Censuses are not conducted in a vacuum. They occur amidst internal and external crisis, shifts in cultural interests, and events that become "defining moments" for each generation. Census data reflect the growth of the population as well as the changing values and interests of the American people.

Fast Facts provides a portrait of the United States both statistically and culturally. In addition to census-related statistics, the innovations, events, and icons of each decade are highlighted. Each page illustrates the thought and culture of the population counted during each decade's census.
