A chloropleth map of Minnesota's 87 counties showing the change in Minnesota's population of residents aged 45-64 years. Darker shaded regions in rural parts of the state have lost a larger share of their population aged 45-64 over the past five years. Much of the Twin Cities is shaded in a lighter shade of purple indicating smaller population losses. A few outer-ring Twin Cities suburbs — including Sherburne, Wright and Scott Counties — are the only counties in the state that have seen an increase in their population of 45-64 year old residents. The largest declines are in western Minnesota (Traverse County) and far northeastern Minnesota (Cook County).
