What exactly is the Austin metropolitan area anyway?
A metropolitan area usually refers to an urban region, connecting principal cities with surrounding territory they have socioeconomic ties with.
For this guide, we'll refer to the definition set by the Office of Management and Budget which dictates the counties and principal cities that make up the Austin metropolitan area, also referred to as Greater Austin.
Five counties make up the Greater Austin area: Williamson, Travis, Bastrop, Caldwell, and Hays.
Bastrop: situated on the east side, this county shares its name with the city of Bastrop.
Caldwell: located southeast, this county has the smallest population out of the five counties.
Hays: on the southwest side, the largest city in the county is San Marcos which also serves as county seat.
Travis: in the center, this county is home to the city of Austin although portions of it also lies in Williamson and Hays.
Williamson: residing in the north, Georgetown serves as county seat although Round Rock is the largest city in the county.
Two cities within Greater Austin are designated as principal cities: Austin, the capital city of Texas, and Round Rock, north of Austin.
