American Community Survey

The American Community Survey from the U.S. Census Bureau is considered the replacement for the census “long form.”  Instead of collecting data every 10 years on education, occupation and other socio-economic characteristics, the ACS happens every year with resulting 1-year, 3-year and 5-year estimates for geographies that meet certain population thresholds.
