The city of Keller added 150 new residents over the past year, according to estimates from the North Central Texas Council of Governments. Keller City Council voted July 2 to adopt 45,090 as its new resident count based on NCTCOG estimates as of Jan. 1, 2019. The city had a population estimate of 44,940 as of Jan. 1, 2018. The new population number reflects a 0.33% increase, according to NCTCOG. But Keller has seen a larger increase over the past nine years. According to the 2010 census, the city had a population of 39,627. Since that time, the city has seen a 13.79% increase in its number of residents. “After rapid population growth in the 1990s and early 2000s, we’ve seen those increases really begin to taper off as we near build-out,” Keller Mayor Pat McGrail said. “The original comprehensive plan for Keller drafted in the 1970s estimated a population of about 50,000 people. I believe the fact that we’re still on course to hit right around that figure is a testament to the vision of our residents and city leaders over many, many years.” 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 NCTCOG, each year cities are asked to provide updates on changes in housing and an estimate of group quarter populations. 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. Lake Worth was the only Tarrant County city to see a drop in population, logging a 0.4% decrease, equal to 20 residents.
