Yes, it is a data gathering program of the Bureau of the Census. From the web site.....
"The American Community Survey is a survey conducted by the U.S. Census Bureau.
Unlike the every-10-year census, this survey continues all year, every year. We randomly sample addresses in every state, the District of Columbia, and Puerto Rico.
Answers are collected to form up-to-date statistics used by many federal, state, tribal, and local leaders. Some American Community Survey questions have been asked by the census since it first began in 1790."
