The American Community Survey (ACS) is an annual national survey collected monthly which provides communities with reliable and timely demographic, housing, social, and economic data every year.
Annual data on Migration is used to determine the extent of residential mobility of the population for the U.S., states, metropolitan areas, and more specific geographical areas that meet minimum population sizes for the given survey year. Data are available from 2000 to the present.
There are more than 25 annual recurring tables on American FactFinder: migration available from American FactFinder since 2000.
Single year estimates for areas size 65,000 and larger are available beginning in 2006 (for data year 2005). Three-year estimates for areas size 20,000 and larger are available beginning in 2008 (for data years 2005-7). Five-year estimates for census groups and larger are available beginning in 2010 (for data years 2005-9).
