Texas' population swelled so much from 2010 to 2020 that it essentially swallowed a state the size of Oklahoma.

Figures released April 26 by the U.S. Census Bureau show Texas gained 3,999,944 residents from April 2010 to April 2020. By comparison, the entire population of Oklahoma totaled 3,959,353 in April 2020. Those nearly 4 million new residents brought Texas' population to 29,145,505 as of April 2020.

Buoyed by a spike in the Hispanic population and an influx of out-of-state and international arrivals, Texas led the nation for the sheer number of residents added from the every-10-years headcount in 2010 to the headcount in 2020. Florida ranked second in that category (2,736,877), and California ranked third (2,284,267).

"The growth for Texas was a little bit slower than expected, which may be a function of lower fertility rates post-Great Recession and slower international migration," Lloyd Potter, the Texas state demographer, tells CultureMap.

California still remains the biggest state as measured by population (39,538,223). However, the Quartz news website reported in 2019 that Texas' population could surpass California's by 2045.

Meanwhile, Texas holds the No. 3 position for percentage population growth from 2010 to 2020, according to Census Bureau data. The state's population shot up by 15.9 percent during that period, behind only Utah (18.4 percent) and Idaho (17.3 percent). By contrast, California saw its population climb by just 6.1 percent from 2010 to 2020.

As a result of population shifts across the country, Texas will pick up two seats in the U.S. House, bringing its total to 38, the Census Bureau says. Five states will add one seat each: Colorado, Florida, Montana, North Carolina, and Oregon. Seven states will lose one seat each: California, Illinois, Michigan, New York, Ohio, Pennsylvania, and West Virginia.

Based on earlier population estimates, experts had expected Texas to tack on three congressional seats following the 2020 Census. But Potter says Texas' growth relative to population changes in other states pared the Lone Star State's final tally to two more seats.

Texas added more residents than any other state in past year

Growing gains

Yes, everything is bigger in Texas — including population growth. From mid-2018 to mid-2019, the Lone Star State added more residents than any other state, new estimates from the U.S. Census Bureau show.

From July 2018 to July 2019, the population of Texas grew by 367,215, according to Census Bureau data released December 30. That's close to the number of people who live in the Dallas-Fort Worth suburb of Arlington (398,112).

Keep in mind that this does not mean nearly 370,000 people moved to Texas in just one year. The Census Bureau's new population estimates represent the number of people who moved to and moved out of each state, as well as the number of births versus deaths.

Texas' 2018-19 population growth eclipsed that of the country's largest state, California.

The Golden State saw its population increase by just 50,635 during the one-year period, the Census Bureau says. What's behind the meager growth? From 2018 to 2019, California's net domestic migration plunged by 203,414. Net domestic migration represents the number of people moving to a state versus the number of people moving out of a state.

Here's another eye opener: Texas accounted for nearly one-fourth of the country's population growth from 2018 to 2019 (1,552,022 people). In that time, 10 states lost population, including Illinois, New Jersey, and New York.

In July 2018, the Texas population stood at an estimated 28,628,666. By July 2019, that figure had climbed to 28,995,881, the Census Bureau says. On a percentage basis, Texas' 2018-19 population growth (1.28 percent) ranked fifth among the states.

Perhaps more impressive is how much Texas expanded from April 2010 (when the last official U.S. headcount was conducted) to July 2019. During that period, Texas added 3,849,790 residents, according to the Census Bureau. To put that into perspective, nearly 4 million people live in the entire state of Oklahoma. Texas' population jumped 15.3 percent from 2010 to 2019, the third highest growth rate behind the District of Columbia and Utah.

Experts cite economic and job growth — along with a low cost of living, a low cost of doing business, and low taxes compared with many other states — as drivers of Texas' population boom. Helping fuel the boom are substantial population spikes in the state's four largest metro areas: Austin, Dallas-Fort Worth, Houston, and San Antonio.

In 2030, the state's population is projected to approach 34.9 million, according to a forecast from the Texas Demographic Center.

Houston's big population boom continues with this many new residents each day

New to HOU

The meteoric rise of the Houston metro area's population continues skyward. From 2017 to 2018, the region added about 251 residents per day, according to population estimates released by the U.S. Census Bureau.

Put another way, the Houston-The Woodlands-Sugar Land region gained 91,689 residents in just one year, the Census Bureau says. That's as if the region absorbed a city around the size of, well, Sugar Land, every 365 days.

All in all, the Houston area ranked third in numeric population growth from 2017 to 2018 among U.S. metro areas with at least 1 million residents, the bureau's estimates show. On July 1, 2017, the bureau counted an estimated 6,905,695 residents in the Houston area. On the same date on July 1, 2018, the area's population stood at 6,997,384. The bureau's estimates take into account people moving into and out of the Houston area, as well as births and deaths.

If you think that growth rate is impressive, consider the Houston area's leap in population from 2010 to 2018.

For that period, Houston ranked second among all U.S. metro areas for population growth on a numeric basis. The Census Bureau says the region's headcount shot up about 18.2 percent from 2010 to 2018, going from 5,920,487 to 6,997,384.

Fort Bend has done its part to feed the Houston area's growth. Among U.S. counties, Fort Bend County ranked 10th for population growth on a percentage basis from 2017 to 2018. The headcount spiked 34.7 percent, from 584,690 to 787,858.

Elsewhere in Texas:

  • Dallas-Fort Worth led U.S. metro areas for numeric growth in population from 2017 to 2018, adding 131,767 residents. In just one year, the region's population rocketed from 7,407,944 to 7,539,711 (1.8 percent).
  • The Austin metro area's population grew 2.5 percent from 2017 to 2018, going from 2,115,230 to 2,168,316, an added 53,086 residents.
  • The population of the San Antonio metro area grew 1.8 percent from 2017 to 2018, going from 2,474,274 to 2,518,036. In that one-year span, the area added 43,762 residents.
  • For 2017 to 2018, Comal County ranked sixth among U.S. counties for percentage growth in population. The number of residents jumped 36.8 percent, from 108,485 to 148,373.
  • In seventh place for percentage population growth among U.S. counties from 2017 to 2018 was Kendall County. The number of residents soared 36.6 percent, from 33,411 to 45,641.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”
