What the numbers mean
Tarrant County's density of about 2602.4 people per square mile is 21.5 times the Texas statewide average of roughly 121. Put another way, there are about 0.25 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.
