The American Community Survey provides a wide range of important statistics about people and housing for every community across the nation. The results are used by everyone from town and city planners to retailers and homebuilders. The survey is the only source of local estimates for most of the 40 topics it covers, such as education, occupation, language, ancestry and housing costs for even the smallest communities. Ever since Thomas Jefferson directed the first census in 1790, the census has collected detailed characteristics about our nation's people. Questions about jobs and the economy were added 20 years later under James Madison, who said [PDF - 3.9 MB] such information would allow Congress to "adapt the public measures to the particular circumstances of the community," and over the decades, allow America "an opportunity of marking the progress of the society."
