The American Community Survey Data Users Group (ACS DUG) is an excellent resource for anyone who needs to access, analyze, interpret, and present data from the American Community Survey. ACS DUG is not managed by the Census Bureau but rather is driven by data users. The Census Bureau participates in many of the meetings. Data users are strongly encouraged to join the ACS DUG. It does not cost anything and is a great resource.
ACS Data Community is an online community that allows people to more easily connect with one another, share ideas, and collaborate.
