Historical definitions 
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. 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.
