Metropolitan Statistical Area
The Springfield metropolitan area was first defined in 1950. Then known as the Springfield Standard Metropolitan Area (Springfield SMA), it consisted of a single county – Clark – and had a population of 111,661. Following a term change by the Bureau of the Budget (present-day Office of Management and Budget) in 1959, the Springfield SMA became the Springfield Standard Metropolitan Statistical Area (Springfield SMSA). By the census of 1960, the population had grown to 131,440, an 18 percent increase over the previous census. Champaign County was added to the Springfield SMSA in 1973. The two-county area had a combined population of 187,606 in 1970.
In 1983, the official name was shortened to the Springfield Metropolitan Statistical Area (Springfield MSA). That same year, Dayton and Springfield were grouped together as the Dayton-Springfield Metropolitan Statistical Area. The new MSA consisted of four counties – Clark, Greene, Miami, and Montgomery. This arrangement remained unchanged until 2003, when the MSA was split with Springfield's newly defined metropolitan area including only Clark County.
