The American Community Survey (ACS) is an annual survey designed to replace the long-form census.
The long-form census is sent out to some households during the census every ten years, and contains more detailed questions than the short-form census.
The ACS will be taken every year, to provide more consistant ongoing information and to allow the census to focus on counting the population. It will be used to help develop programs and services for communites. Information for smaller communities will need to be averaged over 3-5 years to provide more accurate and reliable data
