and Kenton and the Ohio county of Hamilton. As surrounding counties saw an increase in their population densities and the number of their residents employed within Hamilton County, they met Census criteria to be added to the MSA. The Hamilton–Middletown, OH MSA was also formed in 1950 and consisted solely of

. In 1990, the Census changed designation of the areas known as MSAs to Primary Metropolitan Statistical Area (PMSA), and a new Consolidated Metropolitan Statistical Area (CMSA) grouping was created. From 1990 through 2005, the Cincinnati–Hamilton–Middletown CMSA included the Cincinnati–Hamilton, OH–KY–IN PMSA and the Hamilton–Middletown, OH PMSA. As of December 2005, Census terminology changed again, eliminating the PMSA/CMSA terminology. Consolidated Statistical Areas (CSA) combine more than one Core Based Statistical Area (CBSA). Newly defined MSAs (Metropolitan) and µSAs (Micropolitan) Statistical Areas are CBSAs. From 2005 to 2013, the Cincinnati–Middletown–Wilmington CSA included the Cincinnati–Middletown MSA (defined as the old Cincinnati–Hamilton–Middletown CMSA), and Wilmington, OH µSA ( Clinton County, Ohio). In 2013, the CSA was redefined again. The Cincinnati–Middletown MSA was renamed the Cincinnati MSA. The Wilmington, OH µSA remained in the CSA. The Maysville, KY µSA, which had previously consisted of Mason and

Population growth

The metropolitan area's population has grown 8.1 percent between Census 2000 and the 2009 Census population estimate, just under the national population growth rate of 9.2 percent over the same period. This growth rate is about in the middle of the growth rates of other similarly sized mid-western metropolitan areas. For example, the Cleveland metropolitan area lost approximately 2% of population, while Grand Rapids and Louisville both respectively gained 8%, Columbus gained 12%, and Indianapolis gained 14% over the same time period. The 2009 population estimate from the US Census classifies population changes between natural population increases (number of births minus number of deaths) and net migration (the difference between people moving into the region minus those moving out of the region). Natural population increase contributes fundamentally all of Greater Cincinnati's population growth. A small amount of net international migration to the region is offset by a small amount of net domestic migration out of the region.Population Estimates
