The U.S. Census Bureau has released detailed 21-page profiles from the 2007 American Community Survey containing demographic, social, economic and housing characteristics for 79 sub-regions of Michigan. These groupings of counties, communities, or neighborhoods are called "rural statistical areas" (RSAs) because their original purpose was to make data available on an annual basis for non-metropolitan areas.
Despite their name, RSAs encompass the entire state, including metropolitan counties. Some of the most useful RSAs are the ones that correspond to Detroit's planning districts and to the portions of large counties outside major cities.
Every county and community is included in an RSA, and Michigan's RSAs can generally be combined to produce data for the state's 14 Regional Planning Areas. (The only exception is that Region 11 had to be combined with Region 12 because Region 11 has fewer than 65,000 people.)
