The U. S. Constitution (Article I, Section II) requires that there be a census every ten years in order to apportion the seats in the House of Representatives among the states. Census information is also used by federal, state and local governments to assess needs and allocate funding, by academics to study the changing population, by individuals to trace their genealogy, and for many other purposes.

In the United States, a census is taken every ten (10) years, in a year that is evenly divisible by 10. So censuses were taken in 1790, 1800,...1890, 1900, 1910,...1970, 1980 1990, 2000. Other countries take censuses at different times and with different frequencies.
