Some of the fastest-growing places in Austin aren’t exactly places. New data from the U.S. Census Bureau, released Thursday, shows how non-incorporated areas of Central Texas – places without a city government – have grown over the past five years.
Unincorporated areas in Travis County have grown faster than any other county in the region in a five-year span, expanding by 12.5 percent with the addition of 21,483 residents since 2010.
Meanwhile, Hay’s County’s unincorporated areas grew the fastest between 2014-2015, expanding by 3.6 percent with the addition of 2,673 residents to bring the county’s unincorporated population up to 75,704. Over the past five years, this population segment has increased by 10.1 percent with the addition of 6,971 residents. Hay’s county’s total estimated population is 194,739, and it was the fastest-growing county in the U.S. according to data released in December.
Here's how some other local counties fared with unincorporated area population growth last year, and in the past five years:
• Bastrop County’s unincorporated areas grew by 2.6 percent during 2014-2015 with the addition of 1,541 residents to see that segment of its population grow to 60,140 residents. Over the past five years, this segment of the population has grown by 7.3 percent with the addition of 4,109 residents. Its total county population is 80,527.
• Caldwell County’s unincorporated areas added only 449 residents, but it was good enough for the third-fastest rate of growth – 2.4 percent – between 2014-2015 to bring the county's unincorporated population up to 18,979. Over the past five years, Caldwell County’s unincorporated areas have grown by 6.7 percent. Its total estimated population is 40,522.
• Travis County had the third-fastest growth in its unincorporated areas, expanding by 2.1 percent with the addition of 4,026 residents to expand this segment of its population to 192,890.
• Williamson County’s unincorporated areas grew by 1.1 percent, roughly, with the addition of 1,299 residents to grow this segment of its population to 120,733. Over the past five years, the county's unincorporated population has grown by 8.6 percent with the addition of 9,610 residents. Its total county population is 508,514.
The new data was released along with the latest numbers for overall population growth in the region. One suburban city north of Austin is ranked as the fastest-growing metro area in the country.
