The U.S. Census Bureau and Missouri Economic Research and Information Center (MERIC) have released the 2009 population estimates for Missouri's counties. Unfortunately, the estimates continue to show population decline in the region. Not surprisingly, the counties surrounding the Missouri's urban centers are experiencing the most growth (see map). Hopefully the full 2010 Census count will show a reversal of the northwest Missouri population decline.
2009 Estimates (with change from 2000 Census):
Atchison County: 6,036 (-415, -6.5%)
Gentry County: 6,108 (-656, -9.6%)
Holt County: 4,868 (-456, -8.5%)
Nodaway County: 22,130 (+129, +0.6%)
Worth County: 2,014 (-371, 15.6%)
