Nine-County Region

The Nine-County Region (Metro Indianapolis Area) is an informal name to an area comprising nine counties in the center of the U.S. state of Indiana with a population of almost 2 million residents. More specifically, the Nine-County Region describes the agglomeration of the metropolitan area of Indianapolis, the State's capital. It includes Marion, Boone, Hamilton, Madison, Hendricks, Hancock, Morgan, Johnson, and Shelby counties. The counties surrounding Marion are sometimes referred to as the "Doughnut Counties" (referring to the circular shape of the region, with Marion County as the "hole" in the center). It is roughly equivalent to the U.S. Census Bureau's official "Indianapolis-Carmel, IN Metropolitan Statistical Area" , which includes the nine counties plus Brown County; but does not include all of the "Indianapolis-Anderson-Columbus, IN Combined Statistical Area" which adds the Metropolitan Statistical Areas of Anderson, Columbus, Crawfordsville, New Castle and North Vernon.
