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.
The ACS is separate from the Census conducted every 10 years, which is required under the Constitution. Each year, 250,000 ACS surveys are mailed to people across the country, and Census says it asks about age, sex, race, family relationships, income, health insurance, education and disabilities. The Census Bureau also stresses that compliance is mandatory.
