What the numbers mean
Travis County's density of about 1405.1 people per square mile is 11.6 times the Texas statewide average of roughly 121. Put another way, there are about 0.46 acres of land for every resident.
A density this high means most residents live in incorporated cities and continuous suburbs. Population size drives the county's large budget, its many courts and precincts, and its weight in statewide elections — a county of this size elects multiple state representatives on its own.
Travis County in statewide context
By population the county ranks 5th of 254; by land area it ranks 79th; and by density it ranks 6th. It punches above its size — more people than its land area alone would suggest.
Texas's population is extremely concentrated: the ten largest counties hold well over half of all Texans, while more than 150 counties have fewer than 30,000 residents. Travis County is one of those ten.
