Starting in 1790 the U.S. Government has taken a census every 10 years. The only one that is missing is the census of 1890 which was destroyed by fire - although there are fragment of it left. The next one will be taken in 2010.
What is a census? A census is the official counting of the size and characteristics of the population, for social analysis and government planning. A census was first conducted in Victoria in 1854 and the first national census was taken in 1911. Since 1961, a census has been taken every five years. Aboriginal people were not officially included in the national census until 1971.
