Question #4: When to Use ACS data
4. If the same data appear in the 2010 Decennial Census and in the ACS, which should I use?
A. It depends. The decennial census is the most accurate source of data for counts of population and housing because it is based on a full enumeration. And, if the data you want are available from the 2010 Decennial Census, they should be used. However, as time goes on, the 2010 Decennial Census data will quickly become out-of-date in many places, and the ACS may become the better choice. Click to see other Frequently Asked Questions
