Texas is edging closer to a milestone — a population of 30 million.

Estimates released December 21 by the U.S. Census Bureau show the population of Texas grew 1.1 percent between July 1, 2020, and July 1, 2021. During that period, the state added 310,288 residents, going from 29,217,653 to 29,527,941. The tally takes into account births, deaths, people moving to Texas, and people moving out of Texas.

Texas ranked first among the states for the number of residents added from 2020 to 2021, which worked out to 850 new residents per day, and seventh for percentage growth. At 2.9 percent, Idaho ranked first for percentage growth.

If Texas maintains a year-to-year growth rate of at least 1.1 percent, the state might break the 30 million mark sometime in 2022. Driving the state’s continued population explosion are people of color, who’ve made up 91 percent of new Texas residents in the 21st century, according to The Texas Tribune.

Lloyd Potter, the state demographer, says it’s conceivable that Texas could be home to 30 million residents in 2022.

“However, our rate of growth has slowed noticeably between 2020 and 2021, with lower fertility, higher mortality, and less international migration. If we add the same number of people estimated to have been added between 2020 and 2021, then it looks like we’ll come up a bit short of 30 million in 2022,” Potter says.

Throughout the country, the COVID-19 pandemic helped drag down population growth from July 2020 to July 2021. The U.S. population rose just 0.1 percent during that period — the smallest one-year increase since the nation was founded.

“Population growth has been slowing for years because of lower birth rates and decreasing net international migration, all while mortality rates are rising due to the aging of the nation’s population,” Kristie Wilder, a demographer at the Census Bureau, says in a news release. “Now, with the impact of the COVID-19 pandemic, this combination has resulted in a historically slow pace of growth.”

Houston boasts massive population growth among major U.S. metros from 2010 to 2020

there here

If the massive influx of Newstonians is any clue, the population of Greater Houston keeps exploding.

New figures from the U.S. Census Bureau put that growth into clearer perspective. Data from the 2020 Census released August 12 shows Houston at No. 5 (20.3 percent) among the country's 50 largest metro areas in the biggest jump in population from 2010 to 2020.

Houston maintains its position at No. 5 (7,122,240 residents), the Census data notes. For some perspective, Houston was No. 8 (4,944,332) in the 2010 Census.

The Bayou City is also one of the three U.S. metro areas to gain at least 1.2 million residents over the decade. (Dallas-Fort Worth and New York are the others.)

Harris County picked up at least 300,000 residents (638,686) between 2010 and 2020. Tarrant County in North Texas also owns that distinction.

Elsewhere in Texas, Austin now ranks as the 28th most populous metro area in the U.S. (2,283,371 residents), surpassing Las Vegas (ranked 29th, with 2,265,461 residents) and inching closer to 27th-ranked Pittsburgh (2,370,930 residents).

Among the country's 50 largest metro areas, Austin notched the biggest jump in population from 2010 to 2020 (33 percent), with Dallas-Fort Worth at No. 6 (20 percent), and San Antonio at No. 7 (19.4 percent). Austin ranked second among metro areas of all sizes for population growth during the decade, trailing only The Villages, Florida, a 55-and-over retirement community (39 percent).

Dallas-Fort Worth remains the country's fourth largest metro area (7,637,387 residents counted in the 2020 Census) and San Antonio still ranks 24th (2,558,143 residents).

All four of the state's major metros moved up the ranks of the biggest U.S. regions from 2010 to 2020.

Following the 2010 Census, Dallas-Fort Worth was the country's sixth largest metro area (5,121,892 residents), San Antonio stood at No. 26 (1,758,210), and Austin was 37th (1,362,416). In just 10 years, Austin climbed nine spots up the metro population ladder.

Meanwhile, Fort Worth ranked as the fastest-growing big city in Texas between 2010 and 2020 (24 percent), followed by Austin (21.7 percent), Houston (9.8 percent), Dallas (8.9 percent), and San Antonio (8.1 percent).

"Many counties within metro areas saw growth [from 2010 to 2020], especially those in the South and West. However, as we've been seeing in our annual population estimates, our nation is growing slower than it used to," Marc Perry, senior demographer at the Census Bureau, says in a news release.

Texas researchers map out parts of Houston most vulnerable to COVID-19

zooming in

A group of researchers from the University of Texas and the University of Houston have created a mapping tool for identifying which parts of the greater Houston area are at the greatest risk from COVID-19.

"The map offers a comparative look at vulnerabilities across Harris County, and could help policy makers determine how to allocate coronavirus tests and health and safety resources," says Amin Kiaghadi, a research associate at UT's Oden Institute for Computational Engineering & Sciences and postdoctoral fellow at the University of Houston, in a news release.

The study, which is posted on MedRxiv, looked into access to health care, pollutant exposure, and medical insurance coverage. Kiaghadi and two UH professors, Hanadi Rifai and Winston Liaw, concluded that the areas most at risk were in the east and northeastern parts of town — especially industrial areas and high-traffic waterways.

The research showed that the highest risk areas were identified as poorer communities, like the area near the Houston Ship Channel. Consequently, populations with lower risk are in the far west areas of Harris County, which tend to be considered nicer areas. According to the release, around 17 percent of the county's population falls into a risk category.

"I'm really interested to see how decision makers look at these maps," Kiaghadi continues. "They can say 'this specific area is vulnerable to many different things—people living there have lower income, they have or they don't have access to the medical care— and that can change the way that they distribute the resources."

Kiaghadi usually focuses on floodwaters spread contamination, and he postulates that his work in this field had an application within the pandemic.

"We believe that if you're exposed to some chemicals for a long time or you were living in an area with bad air quality, that can affect your immune system long term and then make you more vulnerable to a disease like COVID-19," Kiaghadi says. "So we decided to take a new approach here and show that these factors should be considered."

Based on census data, the map is divided up into 786 polygons and looks into 46 different variables in five categories:

  1. People with limited access to hospitals and medical care.
  2. People with underlying medical conditions.
  3. People with exposures to environmental pollutants.
  4. People in areas vulnerable to natural disasters and flooding.
  5. People with specific lifestyle factors, like obesity, drinking and smoking.

According to the release, the researchers formulated the map within just a couple weeks.

"We already had a lot of knowledge and experience working with this sociodemographic data, and population vulnerability to the flaws in the environment and exposure," Kiaghadi says. "So we felt like, this is totally related to our research, so why not explore what it means?"

Bayou City comes close to topping Census Bureau's list for greatest population boom in the country

so popular

The Lone Star State is proving quite popular, at least according to the U.S. Census Bureau. As reported by numbers released on March 26, Texas is home to cities with the fastest-growing large metro area in the nation and the biggest numeric gain of residents.

Those would be Austin and Dallas-Fort Worth, respectively. And we'll delve into their numbers in a minute, because first it's time to talk about Houston.

H-Town actually nipped at DFW's heels in terms of the numeric population gain from 2010 to 2019. In that time, the Houston area picked up 1,145,654 residents, the second highest total among U.S. metros. That's around the number of people who live in the Buffalo, New York, metro area.

Houston stills holds the No. 5 position on the list of the largest U.S. metro areas. The bureau put its 2019 population at 7,066,141, up 19.4 percent from 2010.

Austin, meanwhile, saw its population shoot up 29.8 percent between 2010 and 2019, landing at 2,227,083 as of July 1, 2019. Put another way, the Austin area added 510,760 residents during the one-decade span.

From 2018 to 2019 alone, the Austin area's population rose 2.8 percent, the Census Bureau says. Numerically, the one-year increase was 61,586 (taking into account births, deaths, new arrivals to the area, and people moving away). That works out to 169 people per day.

Helping drive the Austin area's population spike from 2010 to 2019 were two of the country's fastest-growing counties. Hays County ranked as the second-fastest growing county in the U.S. (46.5 percent) in the past decade, the Census Bureau says, with Williamson County at No. 9 (39.8 percent).

In terms of numeric growth, Travis County ranked 10th in the country from 2010 to 2019 with the addition of 249,510 residents, according to the Census Bureau.

While Austin was the fastest-growing major metro area from 2010 to 2019, Dallas-Fort Worth topped the Census Bureau list for the biggest numeric gain. During that period, DFW welcomed 1,206,599 residents. To put that into perspective, that's about the same number of people who live in the entire Salt Lake City metro area.

On July 1, 2019, DFW's population stood at 7,573,136, up 19 percent from 2010. It remains the country's fourth largest metro, behind New York City, Los Angeles, and Chicago.

Although the San Antonio metro area didn't make the top 10 for percentage or numeric growth from 2010 to 2019, two of the region's counties appeared among the 10 fastest-growing counties:

  • Ranked at No. 4, Comal County's population jumped 43.9 percent.
  • Ranked at No. 5, Kendall County's population rose 42.1 percent.

In the previous decade, the San Antonio area's population climbed 19.1 percent, winding up at 2,550,960 in 2019, the Census Bureau says. Over the 10-year period, the region added 408,440 residents.

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.

Venus Aerospace closes $91M funding round to scale hypersonic engine

flight funding

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were named to the World Economic Forum's Technology Pioneers community earlier this summer. Read more here.

Intuitive Machines lands $148M as part of NASA Moon Base funding

to the moon

Houston-based Intuitive Machines has been awarded $148.3 million to deliver its Nova-C lander to the moon by 2028. The funding is part of $600 million that NASA recently awarded to three companies as part of the agency’s Moon Base Program.

The contracts aim to support sustained human presence and commercial operations on the Moon. Austin-based Firefly Aerospace was awarded $144.2 million by NASA for one mission and Pittsburgh-based Astrobotic netted $297.9 million for two lunar landings. Intuitive Machine's award is the company's sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program.

“We’re building a proving ground for Moon Base operations,” Ryan Stephan, NASA’s Moon Base acting director of cargo landers, said in a news release. “Accelerating our Moon mission ordering cadence and launch opportunities enable us to move quickly to learn, iterate, and improve.”

Under the latest task order, Intuitie Machines will deliver three scientific and operational payloads to the moon, which include a:

  • Linear Energy Transfer Spectrometer (LETS) radiation monitor to gather critical environmental safety data
  • Advanced stereo cameras to analyze surface-plume interactions (SCALPSS)
  • Laser retroreflector array (LRA) for precise cislunar positioning

The funding breakdown includes a $68.6 million base contract and a $79.7 million performance incentive for Intuitive Machines.

The company says the funding will allow it to create a standardized and repeatable "lunar utility pipeline" for delivering cargo to the moon.

"We are shifting the paradigm from custom aerospace engineering to commercial mass production of lunar infrastructure," Steve Altemus, CEO of Intuitive Machines, said in a separate news release. "Our flight-proven Nova-C platform allows us to build, test, and deploy multiple landers in parallel using Industry 4.0-powered manufacturing. This contract directly advances our core mission to provide persistent, reliable, and commercial baseline of transport, connectivity, and operations that allows our customers to stay longer and achieve more on the Moon."

NASA also shared that it is exploring plans to send PROMISE, a rover based on the Mars Perseverance and Curiosity rovers, to the moon and it plans to seek proposals for additional lunar lander missions, technology demonstrations, a communications and navigation satellite network, and new science payloads to support its lunar outpost. NASA is developing its Moon Base near the lunar South Pole. The agency expects it to come to fruition sometime after 2032.

Intuitive Machines had received its last CLPS award for $180.4 million in March 2026. It will be the first mission to utilize the company's larger cargo lunar lander, Nova-D. The company was also recently awarded a $1 million grant from Maryland Gov. Wes Moore to expand its robotics operations in the state.

UT team develops wearable technology for atmospheric water harvesting

In The Air

Engineers at the University of Texas at Austin have developed a prototype jacket that harvests clean drinking water directly from the atmosphere, and it works even in the driest desert conditions.

The research, published in Science Advances, marks the latest milestone in nearly a decade of work by materials scientist and chair professor Guihua Yu and his team at the Cockrell School of Engineering's Walker Department of Mechanical Engineering and Texas Materials Institute. The wearable technology marks a significant leap: instead of a bulky, stationary machine, this jacket does the work.

"We have been working on atmospheric water harvesting technology for a number of years," Yu says. "This current version is even more wearable. We're transitioning from conventional, more stationary water harvesting to something truly portable and personal."

Yu's lab first published work on hydrogel-based water harvesting around 2019, and the jacket is the latest evolution of that platform, now called AirGel. Last year, the broader AirGel invention won the top prize in the graduate category of the National Collegiate Inventors Competition.

The jacket is woven with specially engineered hydrogel fibers; ultra-porous materials that attract and absorb moisture from the surrounding air much like a household desiccant. Unlike a desiccant, the material doesn't require intense heat to release that water. The hydrogel is thermally responsive, meaning a modest rise in temperature — even from mild solar heating — is enough to release the water it has captured.

Condenser test in AustinSo, somebody would be wearing the jacket, or perhaps carrying this gel-like textile as a blanket, as it passively absorbs moisture from the air. Then they would detach the textile panels and place them into a small, portable collector unit; essentially a compact heater. The water evaporates out of the textile, condenses inside the collector, and drips out as clean, drinkable water.

"It immediately becomes drinkable because it already goes through the distillation process," Yu explains.

In trials, the jacket produced between 400 and 900 milliliters of water per day depending on humidity, or roughly 14-30 ounces, nearly a quart, depending on the air's humidity. With one kilogram of the textile, the researchers found they could generate approximately 3.7-4 liters of water in arid conditions, and potentially double that in humid ones. So far, the team has tried the jacket out in very dry, semi-dry, and humid areas, and the jacket was able to pull water from each climate.

Lead researcher Chuxin Lei, a postdoctoral researcher on Yu's team and co-author on the paper, says the goal was to rethink who this technology could serve.

Portable bag contents

"Many current [atmospheric water harvesting] systems are still built as rigid or stationary platforms, making them less suitable for people who are moving, working outdoors, or operating in some remote environment. This lead us to ask whether we could build a water harvesting system that could become more like clothing — light, wearable, flexible, and naturally suited for personal use," Lei says.

The potential applications are wide-ranging. Yu's team has previously worked with the Department of Defense on water solutions for soldiers, where water logistics can be dangerous and costly. The technology could also serve hikers, emergency responders, disaster relief workers, and agricultural and field workers. Anyone who needs clean water on the go and far from infrastructure.

The team also sees a potential future where the technology complements large-scale centralized water systems rather than replacing them.

"Our solution cannot be a universal solution for all," Yu acknowledges. "But I think it's an extremely important alternative."

For now, the jacket is still a laboratory prototype, but Yu and Lei are optimistic. With the right industry partnerships, they say, the technology could realistically reach commercial scale within three to five years.
