Des Moines metropolitan area
From Wikipedia, the free encyclopedia
The Des Moines metropolitan area, officially known as the Des Moines-West Des Moines Metropolitan Statistical Area (MSA), consists of five counties in central Iowa: Polk, Dallas, Warren, Madison, and Guthrie. The 2000 census population of these counties was 481,394, and the 2005 estimated population was 522,454.[1]
Two additional counties, Jasper and Marion, are part of the Des Moines-Newton-Pella Combined Statistical Area (CSA). The area encompasses the separate micropolitan areas of Newton (Jasper County) and Pella (Marion County). The total population of the CSA was 550,659 in the 2000 census and 593,112 based on 2005 estimates.[2]
Polk County was originally the only county in the Des Moines metropolitan area when the United States Bureau of the Budget (now the United States Office of Management and Budget) began defining metropolitan areas in 1950. Warren County was added in 1973 and Dallas County was added in 1983. [3] Guthrie and Madison counties were added in 2003 after metropolitan areas were redefined. In 2005 the area was renamed the Des Moines-West Des Moines Metropolitan Statistical Area after a special census showed that West Des Moines had topped the 50,000 mark in population.[4]
