Williamson County Covers 1,137 Square Miles and Has Nearly 500,000 Residents

Williamson County covers 1,137 square miles. It sits in Central Texas, about 25 miles north of Austin. As of 2014, about 489,000 people lived here. Growth has kept going since then.

The county started growing fast in the 1970s. Austin's suburbs pushed north along the I-35 corridor. Towns like Round Rock, Cedar Park, and Leander expanded quickly as people moved out of Austin.

That growth changed the county. It went from a farming economy to a mix of suburbs, tech companies, and some remaining farmland. If you are moving here, you will find older small-town areas like Georgetown and Taylor sitting alongside fast-growing suburban cities.
