Over the past year, Grapevine added 2,130 residents, according to the report. Colleyville added 360 residents and Southlake added 430 residents, the report said.
But Grapevine, Colleyville and Southlake have seen larger increases over the past nine years, with Southlake leading the way. According to the 2010 census, the city had a population of 26,575. Since that time, Southlake has experienced a 12.93% increase in its number of residents.
Over the past nine years, Grapevine has seen a 10.87% increase in its number of residents, and Colleyville has seen an 11.24% increase, according to NCTCOG data.
Both Southlake and Colleyville credited their growth in part to the large lots their cities offer to residents.
"When I spoke to the real estate folks, they said the most attractive things are the large lots and the convenience of shopping and dining here," said Daniel Cortez, Southlake's deputy director of economic development.
In Colleyville, the redevelopment of older homes will probably play a factor in the city's growth, Assistant City Manager Mark Wood said.
"People want to locate in Colleyville because of the large lots, open feel, and community-atmosphere," Wood said in an email. "A lot of our subdivisions are filling in and we have seen significant interest in redevelopment of older homes. We believe the residential redevelopment will be the next opportunity for the city."
Grapevine's central location has played a role in the city's growth, Economic Development Director Bob Farley and Business Retention Manager Garin Gaicomarro said in an email.
"Grapevine is a beneficiary of the huge influx of people that metros in Texas are seeing," they said in the email. "Our location makes us a prime spot for people coming to Texas, and our collection of services make us an attractive landing place."
Tarrant County’s total population growth of 27,463 in the last year was fueled by 12,618 residents moving into the area; 8,312 of those residents moved to the area came from outside the U.S., and 4,306 relocated domestically, according to data from the U.S. Census Bureau.
The NCTCOG bases its population estimates on housing units. It uses a formula that incorporates a city’s number of estimated housing units, estimated occupancy rate and estimated number of persons per occupied unit.
The results also include an estimate of residents in group quarters. Group quarters are places owned or operated by organizations providing housing and services for residents.
According to the NCTCOG, each year cities are asked to provide updates on changes in housing and an estimate of group quarters populations.
The NCTCOG encompasses a 16-county area and helps local governments with regional planning. Among other cities in Tarrant County, Westlake saw the largest population change between 2018-19, with a 16.7% increase.
