A census worker visits a household in Fairbanks, Alaska to log their information for the 1940 census, helping the country know exactly how many citizens it has, and how they're spread out. Eighty years later, citizens can fill the census out online, but households that do not submit a census by Aug. 11 should still expect a visit from a census worker.
