Houston saw the second-highest population increase in the United States in 2024, according to the U.S. Census Bureau.

The new population report revealed Houston gained 43,217 residents from July 2023 to July 2024, bringing the city's population to 2,390,125.

Houston hung on to its ranking as the fourth largest city in the country and joined 11 other Southern cities that saw the largest numeric population gains in 2024, the report added.

Elsewhere in Texas, Fort Worth is now home to more than 1 million residents, surpassing Austin as the 11th largest city in the U.S. Fort Worth had the fifth-highest numeric increase in population, adding 23,442 residents during that same time frame to bring the city's total population to 1,008,106 residents.

Dallas retained its No. 9 spot on the list of the 15 most populous cities in the U.S. The city gained more than 23,000 residents during the one-year period, bringing its population to 1,326,087 people in 2024.


Austin slipped two spots and now ranks as the 13th largest city after adding more than 13,000 residents to bring the Texas Capital's population to 993,588.

San Antonio gained 23,945 residents — the fourth-highest increase nationwide — and was the only other city besides Houston to have a higher numerical growth rate than Fort Worth during the one-year period.

Fastest-growing U.S. cities
Princeton, a North Texas suburb of Dallas, topped the charts as the No. 1 fastest-growing U.S. city in 2024. The Census Bureau says the city's population has more than doubled in the last five years to more than 37,000 residents.

Fulshear, 34 miles from downtown Houston, has continued its rapid expansion as the second-fastest growing city. The suburb grew nearly 27 percent since the previous year, and its population rose to 54,629 residents as of July 2024.

Five additional Texas cities made the list of fastest-growing U.S. cities:

  • Celina, near Dallas (No. 4) with 18.2 percent growth (51,661 total population)
  • Anna, near Dallas (No. 5) with 14.6 percent growth (31,986 total population)
  • Fate, near Dallas (No. 8) with 11.4 percent growth (27,467 total population)
  • Melissa, near Dallas (No. 11) with 10 percent growth (26,194 total population)
  • Hutto, near Austin (No. 13) with 9.4 percent growth (42,661 total population)

The Austin suburb of Georgetown's growth has continued to slow down since 2023, and it no longer appears in the list of fastest-growing cities. However, it did surpass 100,000 residents in 2024. San Angelo, a small city in West Texas, also surpassed the 100,000-population threshold.

Most populous U.S. cities in 2024
New York City maintained its stronghold as the biggest in America in 2024, boasting a population of nearly 8.5 million residents. Los Angeles and Chicago also retained second and third place, with respective populations of nearly 3.88 million and more than 2.7 million residents.

"Cities in the Northeast that had experienced population declines in 2023 are now experiencing significant population growth, on average," said Crystal Delbé, a statistician in the Census Bureau’s Population Division. "In fact, cities of all sizes, in all regions, showed faster growth and larger gains than in 2023, except for small cities in the South, whose average population growth rate remained the same."

The 15 populous U.S. cities as of July 1, 2024 were:

  • No. 1 – New York, New York (8.48 million)
  • No. 2 – Los Angeles, California (3.88 million)
  • No. 3 – Chicago, Illinois (2.72 million)
  • No. 4 – Houston, Texas (2.39 million)
  • No. 5 – Phoenix, Arizona (1.67 million)
  • No. 6 – Philadelphia, Pennsylvania (1.57 million)
  • No. 7 – San Antonio, Texas (1.53 million)
  • No. 8 – San Diego, California (1.4 million)
  • No. 9 – Dallas, Texas (1.33 million)
  • No. 10 – Jacksonville, Florida (1 million)
  • No. 11 – Fort Worth, Texas (1 million)
  • No. 12 – San Jose, California (997,368)
  • No. 13 – Austin, Texas (993,588)
  • No. 14 – Charlotte, North Carolina (943,476)
  • No. 15 – Columbus, Ohio (933,263)

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

Houston ranks among top 5 cities for corporate HQ relocations in new report

h-town HQ

The Houston area already holds the title as the country’s third biggest metro hub for Fortune 500 headquarters, behind the New York City and Chicago areas. Now, Houston can tout another HQ accolade: It’s in a fourth-place tie with the Phoenix area for the most corporate headquarters relocations from 2018 to 2024.

During that period, the Houston and Phoenix areas each attracted 31 corporate headquarters, according to new research from commercial real estate services company CBRE. CBRE’s list encompasses public announcements from companies across various sizes and industries about relocating their corporate headquarters within the U.S.

Of the markets included in CBRE’s study, Dallas ranked first for corporate relocations (100) from 2018 to 2024. It’s followed by Austin (81), Nashville (35), Houston and Phoenix (31 each), and Denver (23).

According to CBRE, reasons cited by companies for moving their headquarters include:

  • Access to lower taxes
  • Availability of tax incentives
  • Proximity to key markets
  • Ability to support hybrid work

“Corporations now view headquarters locations as strategic assets, allowing for adaptability and faster reaction to market changes,” said CBRE.

Among the high-profile companies that moved their headquarters to the Houston area from 2018 to 2024 are:

  • Chevron
  • ExxonMobil
  • Hewlett-Packard Enterprise
  • Murphy Oil

Many companies that have shifted their headquarters to the Houston area, such as Chevron, are in the energy sector.

“Chevron’s decision to relocate its headquarters underscores the compelling advantages that position Houston as the prime destination for leading energy companies today and for the future,” Steve Kean, president and CEO of the Greater Houston Partnership, said in 2024. “With deep roots in our region, Chevron is a key player in establishing Houston as a global energy leader. This move will further enhance those efforts.”

According to CBRE, California (particularly the San Francisco Bay and Los Angeles areas) lost the most corporate HQs in 2024, with 17 companies announcing relocations—12 of them to Texas. Also last year, Texas gained nearly half of all state-to-state relocations.

In March, Site Selection magazine awarded Texas its 2024 Governor’s Cup, resulting in 13 consecutive wins for the state with the most corporate relocations and expansions.

In a news release promoting the latest Governor’s Cup victory, Gov. Greg Abbott hailed Texas as “the headquarters of headquarters.”

“Texas partners with the businesses that come to our great state to grow,” Abbott said. “When businesses succeed, Texas succeeds.”

CBRE explained that the trend of corporate HQ relocations reflects the desire of companies to seek new environments to support their goals and workforce needs.

“Ultimately, companies are seeking to establish themselves in locations with potential for long-term success and profitability,” CBRE said.

SpaceX test rocket explodes in Texas, but no injuries reported

SpaceX Update

A SpaceX rocket being tested in Texas exploded Wednesday night, sending a dramatic fireball high into the sky.

The company said the Starship “experienced a major anomaly” at about 11 pm while on the test stand preparing for the 10th flight test at Starbase, SpaceX’s launch site at the southern tip of Texas.

“A safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for,” SpaceX said in a statement on the social platform X.

CEO Elon Musk ’s SpaceX said there were no hazards to nearby communities. It asked people not to try to approach the site.

The company said it is working with local officials to respond to the explosion.

The explosion comes on the heels of an out-of-control Starship test flight in late May, which tumbled out of control. The FAA demanded an investigation into the accident.

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.
