The area of the Grass Lake Regional Chamber of Commerce is fairly large when considering the membership and the area of coverage of the market area. However, in 2005 the Village of Grass Lake Downtown Development Authority conducted a market study to derermine the actual demographics for the area considering its market to run north into Waterloo Township, south into Napoleon Township, west into Leoni Township and east into Sylvan Township in Washtenaw County. Accordingly, the data sheet below reflects that wide and varied demographic data for the area the Chamber covers.
