Harris County booms with 3rd biggest population in U.S.

Boomtown

Newly released U.S. Census Bureau data has revealed Harris County became the third most populous county nationwide in 2024, and it had the highest year-over-year growth rate from 2023.

The new population report, published this month, estimated year-over-year population data from 2023 to 2024 across all 3,144 U.S. counties, and 387 metro areas.

Harris County's numeric growth rate outpaced all other U.S. counties from July 1, 2023 to July 1, 2024, the report found. The Census Bureau estimated Harris County's population grew by 105,852 people year-over-year, bringing the total population to 5,009,302 residents. That's around a 2.16 percent growth rate.

Los Angeles County, California (No. 1) and Illinois' Cook County (No. 2) are the only two U.S. counties that have larger populations than Harris County. Los Angeles County now boasts a population of nearly 9.76 million, while Cook County's has increased to more than 5.18 million people.

The top 10 most populous counties in the U.S. are:

  • No. 1 – Los Angles County, California
  • No. 2 – Cook County, Illinois
  • No. 3 – Harris County, Texas
  • No. 4 – Maricopa County, Arizona
  • No. 5 – San Diego County, California
  • No. 6 – Orange County, California
  • No. 7 – Miami-Dade County, Florida
  • No. 8 – Dallas County, Texas
  • No. 9 – Kings County, New York
  • No. 10 – Riverside County, California

Montgomery County also ranked among the top 10 U.S. counties with the highest numeric growth, ranking 9th nationally after gaining 34,268 residents from 2023 to 2024. Montgomery County's population has now grown to 749,613 people.

In the report's national comparison of counties with the largest population growth by percentage, Montgomery County ranked No. 7 with a year-over-year growth rate of 4.8 percent.

Most populated U.S. metro areas

The U.S. Census Bureau additionally found Houston-Pasadena-The Woodlands nearly led the nation as the second-fastest growing metro area in 2024.

From July 2023 to July 2024, the Houston metro added 198,171 residents to bring the total population to 7,796,182.

New York-Newark-Jersey City was the only metro area to outpace Houston's growth during the one-year period. The New York-New Jersey metro added 213,403 new residents, which brought the total population to over 19.94 million last year.

Kristie Wilder, a Census Bureau Population Division demographer, said in the report that the nation's population growth in its major metros was largely impacted by international migration rather than changes in birth rates.

"While births continue to contribute to overall growth, rising net international migration is offsetting the ongoing net domestic outmigration we see in many of these areas," Wilder said.

Dallas-Fort Worth-Arlington was right behind Houston as the third-fastest growing U.S. metro in 2024. The Metroplex gained 177,922 residents last year, and now has a total population of more than 8.34 million.

The top 10 U.S. metros with the highest numeric growth from 2023 to 2024 are:

  • No. 1 – New York-Newark-Jersey City, New York-New Jersey
  • No. 2 – Houston-Pasadena-The Woodlands, Texas
  • No. 3 – Dallas-Fort Worth-Arlington, Texas
  • No. 4 – Miami-Fort Lauderdale-West Palm Beach, Florida
  • No. 5 – Washington-Arlington-Alexandria, D.C.-Virginia-Maryland-West Virginia
  • No. 6 – Phoenix-Mesa-Chandler, Arizona
  • No. 7 – Orlando-Kissimmee-Sanford, Florida
  • No. 8 – Atlanta-Sandy Springs-Roswell, Georgia
  • No. 9 – Chicago-Naperville-Elgin, Illinois-Indiana
  • No. 10 – Seattle-Tacoma-Bellevue, Washington

Education equity-focused nonprofit taps into robotics, AI to better serve Houston children

the future is bright

Generally, when children are under the age of five, educators believe that they are best suited for and interested in learning, because those are the years in which there is the strongest opportunity to build a broad and solid foundation for lifelong literacy and well-being.

That sentiment is deeply held by Collaborative for Children, the Houston-based nonprofit organization with the mission to meaningfully improve the quality of early childhood education and provide access to cutting-edge technology through its Centers of Excellence to all children, especially those in low-income and marginalized communities.

“The reason the organization was started about 40 years ago is that a group of philanthropists in the greater Houston area suggested that this was so important because 90 percent of the brain develops or grows in the time frame between ages zero to five years of age,” Melanie Johnson, president and CEO of Collaborative for Children, tells InnovationMap.

“And if we were losing children and not preparing them by third grade to be literate, and then subsequently losing them after that for high dropout rates and achievement gaps between poor and affluent children, that this would be the perfect place to start," she continues. "And so, they put the collaborative, the emphasis, and finances collaborative of every, most every early education effort around this region.”

Collaborative for Children’s work in the community is centered around making sure that there is educational equity for all children, regardless of financial status, and providing access to technologies in meaningful ways.

“Ultimately, we want to bridge the digital divide early on so that when children start off their academic journey, they're starting off equipped with the skills to be successful there on,” says Johnson.

Most recently, the institution has focused on utilizing social-emotional learning robots and coding tech toys like the Pepper — the world’s first social humanoid robot able to recognize faces and basic human emotions — and NAO, which resembles human being and stimulates, robots to enhance learning in the classrooms of its Centers of Excellence.

“Technology enhances the learning experience in the Centers of Excellence in ways that a teacher might not be able to,” says Johnson. “Artificial intelligence is used in gamification to allow a child to play and learn while playing.”

For Collaborative for Children, gamification involves transforming typical academic components into gaming themes.

“While playing, the AI gauges the level of skills that they’ve been able to enter into that system and respond with even more challenging tasks or tasks that are still lateral so that they can continue to repeat that skill,” says Johnson.

The socio-emotional learning robots are indeed fascinating, but how does the nonprofit reach these children, and their parents, who might be skeptical of technology?

Ultimately, through the teachers. They draw them in via the technology. If teachers are excited, they act as a conductor of that energy to their students, making their innovative lessons well, electric.

That resonates with most all children, but especially with those diagnosed with autism.

“Robotics like NAO are great for children on the autism spectrum because they are emotionally sensitive and emotionally intelligent,” says Johnson. “They are low sensory, so as NAO runs around the classroom, it can literally have individual and unique conversations with each child based on facial recognition. But most importantly for me, is that this particular robot is able to evaluate children without statistical bias that a teacher might have.

“A teacher might think that because a child confuses the letter D and B, which are basically shaped the same in opposite directions, that they're not learning," she continues. "And the robot will have no prior knowledge in terms of, is this child the better child, or have they been learning throughout the year? The answers are accurate or inaccurate. So, they remove statistical bias when assessing children in the classroom.”

The misconception about teaching technologies is that it’s about screen time. According to Johnson, it’s not. It’s more about interacting with technology.

“We’ve added, you know, all kinds of modern-day technology so that this world that we're preparing these children for 80 percent of the jobs we don't even know will exist when they are adults,” says Johnson. “So, we're just trying to make sure that there is no divide in terms of 21st century skills and 21st century preparation.”

Building Blocks Ep. 12youtu.be

Collaborative for Children has so many facets to assist children with their early development, but there are inherent challenges when attempting to reach their target audience in low-income and marginalized communities that the organization counters with programs like the Collab Lab, which is a mobile classroom that brings critical, future-focused early childhood education directly to the community at no cost.

Designed to be convenient for families, Collab Lab connects parents and their youngest children with experts, educators, resources, and proven programs whose goal is to make sure that kids have the skills essential to learning from the moment they walk into kindergarten for the first time.

“There are a myriad of challenges in these communities that we serve, specifically with technology,” says Johnson. “When children enter first grade, and especially second grade, they're given notepads, basically, digital notepads, because it's no good in pre-K oftentimes, but it is very helpful for children who will never have access or have limited access to iPads and things of that nature.

“So while we don't want them to be babysat by screen time and have social media impacting their self-image and self-worth, we definitely want them to have appropriate doses and appropriate uses of technology in the early education, so that those barriers that their parents face with limited means, that these children can go to first grade and into the robotics class and be able to be evaluated and assessed on the digital notepads that are required nowadays,” she continues.

While technology is very important, Collaborative for Children also focuses on the critical social and emotional skills children need as they develop and the all too important relationship between children and their parents and teachers.

“Theory leads our work,” says Johnson. “It's all focused on fine motor skills, gross motor skills, social emotional, can a child build rapport with their teacher and with the students around them. Those things are paramount and will never change.

“What we use technology to do is enhance and remove biases from teacher-pupil interaction, but also to bridge any kind of divide in terms of 21st century skills. And in addition to that, we engage the families. So families who might not know about hydro-fueled cars in those communities that we serve will be able to be exposed to those concepts, as well through our group connections or parent partnerships.”

Ultimately, the last thing Collaborative for Children wants is to send children from early learning and childcare environments into the K-12 system unprepared to be successful for the real world.

“At Collaborative for Children,” adds Johnson. “We are continuously pushing the envelope at our Centers for Excellence so that the children that we serve will always be on the cutting edge.

Houston named 4th most populous city in U.S. — with the greatest housing growth — in new Census report

welcome, newstonians

Houston is the fourth most populous U.S. city, and saw the ninth largest numeric population gain of any U.S. city in 2022, according to the U.S. Census Bureau's latest findings.

From July 2021 to July 2022, Houston added 11,223 new residents, bringing its total population to 2,302,878. By comparison, San Antonio (population just under 1.5 million) is the seventh largest.

Harris County also led the way with the highest numeric gains for housing units in the nation, at 32,694, coinciding with recent reports deeming Houston the most active real estate market within the last decade.

Together, Houston-The Woodlands-Sugar Land ranked No. 5 in the list of the 10 most populous U.S. metro areas (as opposed to the cities, themselves). Dallas-Fort Worth-Arlington ranked one place higher at No. 4.

Texas cities and towns dominated every list in the new Census Bureau report. "Texas was the only state that had more than three cities on both the 15 fastest-growing large cities and towns by numeric change and by percent change lists," the report says.

Fastest-growing cities
Six out of the 15 fastest-growing cities in the United States are in Texas, and with one Houston suburb – Conroe – landing at No. 11. Conroe had an 6.3 percent population increase from July 2021 to July 2022, bringing the city's total population just over 101,400.

The north Austin suburb of Georgetown had the highest growth rate in the nation, at 14.4 percent, bringing the city's total population to more than 86,500 residents. Surrounding Austin suburbs Kyle and Leander landed in No. 3 and No. 4 with the same population growth rate of 10.9 percent.

The not-so-little Dallas suburb Little Elm zoomed all the way up to No. 5 with an 8 percent population increase, bringing the city's total population to more than 55,300 residents. New Braunfels, which is outside San Antonio, came in at No. 13.

The top 15 fastest-growing large cities in the U.S. are:

  • No. 1 – Georgetown, Texas
  • No. 2 – Santa Cruz, California
  • No. 3 – Kyle, Texas
  • No. 4 – Leander, Texas
  • No. 5 – Little Elm, Texas
  • No. 6 – Westfield, Indiana
  • No. 7 – Queen Creek, Arizona
  • No. 8 – North Port, Florida
  • No. 9 – Cape Coral, Florida
  • No. 10 – Port St. Lucie, Florida
  • No. 11 – Conroe, Texas
  • No. 12 – Maricopa, Arizona
  • No. 13 – New Braunfels, Texas
  • No. 14 – Lehi, Utah
  • No. 15 – Medford, Massachusetts
Largest population increases
When it comes to most populous cities overall, Texas takes five of the 15 top spots with Houston claiming No. 1 in the state. After Houston's No. 4 national rank with its population of over 2.3 million, San Antonio earned No. 7 with over 1.47 million residents, and Dallas at No. 9 with just under 1.3 million residents. Austin barely made it into the top 10 with over 974,000 residents, and Fort Worth ranked No. 13.

The top 15 most populous American cities are:

  • No. 1 – New York City
  • No. 2 – Los Angeles
  • No. 3 – Chicago
  • No. 4 – Houston
  • No. 5 – Phoenix
  • No. 6 – Philadelphia
  • No. 7 – San Antonio, Texas
  • No. 8 – San Diego, California
  • No. 9 – Dallas
  • No. 10 – Austin, Texas
  • No. 11 - Jacksonville, Florida
  • No. 12 - San Jose, California
  • No. 13 - Fort Worth, Texas
  • No. 14 - Columbus, Ohio
  • No. 15 - Charlotte, North Carolina

Greatest housing growth
The report also discovered that housing inventory skyrocketed by 1.6 million units between 2021 and 2022. Texas had the third fastest housing growth with a rate of 2.3 percent, versus Utah, which had the fastest growth at 3.3 percent.

In addition to Harris County, the only other Texas county that made the top five for the highest housing growth was Travis (No. 3).

The waitlist will still put those at high risk in priority. WPA Pool / Getty Images

Harris County rolls out new COVID-19 vaccination waitlist

WORTH THE SHOT

Harris County Judge Lina Hidalgo announced a new COVID-19 vaccine waitlist on January 25, in an effort to ensure those who are high priority don't get overlooked and make for a smoother process.

Hidalgo explained the basics of how the waitlist will work. She was joined by Dr. Sherri Onyiego, the interim local health authority for Harris County Public Health.

The waitlist, which can be found at ReadyHarris, is said to be weighted and randomized, meaning the website won't necessarily favor whoever has the quickest internet connection. Once the portal opens Tuesday, January 26, everyone will be able to register.

If you fall under the 1A, 1B or seniors groups, then your registration will be weighted for priority, and it will then be randomized within the priority list.

The launch of this new portal and waitlist expands the previous process by allowing eligible residents to sign up for vaccines on their own directly, according to a press release from the county.

Eligible residents without internet access can also call 832 927-8787 once the portal is live to be placed on the waitlist.

If you do not fall under those three groups, you will still be able to register, but it means you'll be on a waitlist for when the vaccine opens to the general public.

In addition to the new portal, the public health department will also be launching a COVID-19 vaccine data hub. The hub will show vaccine availability, distribution, and other demographic data.

Over 400 small businesses in the Houston area have been granted forgiveness for loans. Photo via Getty Images

Harris County forgives hundreds of small business loans for struggling locals

Granting a reprieve

The global pandemic has wreaked havoc on local small businesses; many have struggled without savings, credit, and capital to continue on during the downturn. For some immediate relief, Harris County and the Houston-Galveston Area Council (HGAC) offered some 444 area small businesses interest-free loans of up to $25,000 earlier this year.

The loans would be forgiven in five years, per the initial Harris County COVID-19 Forgivable Loan Program agreement.

Now, in some feel-good, holiday news, the loans have been converted into grants, thanks to federal CARES Act funding received by the county, according to a statement by Harris County and Houston-Galveston Area Council.

"Many of the owners have already made use of the funds they received. Knowing that they don't have to pay it back, that it's all theirs, gives them one less thing to worry about at a time when so many have been impacted," said Omar Fortune, manager of the Houston-Galveston Area Local Development Corporation (H-GALDC), in a statement. (The organization handled the underwriting process and distribution of loans to small businesses.)

"We're pleased to be able to provide this gift to these small businesses that are so important to our region. That it's happening during the holiday season makes it even more special."

Originally launched on April 9, the Harris County COVID-19 Forgivable Loan program distributed $10 million to the 444 small businesses by the summer. On October 6, Harris County approved the loan conversion to grants, according to a press release. Small businesses that had already begun paying back their loans have had their payments reimbursed by the county, according to HGAC.

Local business owners are "ecstatic" upon hearing the news, according to H-GAC. " This whole experience has been an emotional roller coaster, but I'm extremely positive about the future," said Museum District-area dentist, Dr. Randy Mitchmore, in a statement.

"I'm proud to own a small business, and we have a direct impact on the local community. I'm also grateful for this program and that it was able to help small businesses as intended."

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.

Houston ranks among world’s top 30 emerging startup ecosystems

Startup Status

Long known as the Energy Capital of the World, Houston also ranks among the world’s top 30 emerging startup ecosystems, according to a new report.

The report from Startup Genome, a research and advisory organization, doesn’t assign a specific numeric ranking to Houston’s startup ecosystem. Rather, it puts Houston in the ranking range of 21 to 30 for emerging ecosystems. Startup Genome weighed factors such as early-stage funding, performance and talent to identify the top emerging ecosystems.

Houston also gained notice for being one of the world’s 20 emerging ecosystems with at least four unicorn startups in the past 10 years. Houston and nine other ecosystems each had four unicorns.

According to StartupBlink, a startup research platform, Houston’s startup ecosystem grew 24 percent in 2025, with over 1,300 startups and total startup funding exceeding $808 million. StartupBlink places Houston at No. 46 among the world’s top 100 startup ecosystems.

In a recent post on LinkedIn, David Horsup, executive in residence at the Rice Alliance Clean Energy Accelerator, wrote that Houston “has all the ingredients to be wildly successful if it stays true to its differentiated pillars that drive the economy — energy, medical, and aerospace.”

Mumbai topped Startup Genome’s list of emerging ecosystems, followed by Istanbul, Madrid, Salt Lake City-Provo and Barcelona. After Salt Lake City-Provo, the top U.S. ecosystems were Phoenix, Detroit, Minneapolis and Las Vegas.

Silicon Valley led Startup Genome’s ranking of the world’s top established ecosystems, followed by New York City, London, Tel Aviv and Boston. Austin landed at No. 18 in this category and Dallas at No. 27.

“For much of the past decade, this report has chronicled the welcome dispersion of opportunity beyond the traditional hubs,” Startup Genome writes. “That trend has not died — but it has been complicated. Capital and scale are consolidating once more, particularly in the United States, and the gap between leading and emerging ecosystems is widening.”
