Census Shows Decrease in County Population

By Travis Volz

Washington County’s population is getting smaller and older, according to information collected last year by the United States Census Bureau.

The county’s population contracted from 14,716 in 2010 to 13,887 in 2020, a decrease of 5.6 percent over the decade.

Every town and village in the county lost population except Addieville, which had a modest increase of 2.78 percent, from 252 in 2010 to 259 in 2020.

The two most populous towns, Nashville and Okawville, each lost just over four percent of their populations over the period. Nashville dropped from 3,258 to 3,105 (4.7 percent decrease), while Okawville fell from 1,434 to 1,369, a decrease of 4.53 percent.
