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

Here's what it takes to be a middle class earner in Houston in 2024

by the numbers

No one wants to hear that they aren't making enough money to be considered "middle class," but those income ceilings are getting more difficult to maintain year after year across the Houston area. And a new report has revealed The Woodlands has the No. 10 highest income ceiling for American middle class earners in 2024.

According to the 2024 edition of SmartAsset's annual "What It Takes to Be Middle Class in America" report, middle class households in The Woodlands would need to make between $91,548 and $274,670 a year to be labeled "middle class." Additionally, the suburb's median middle class household income comes out to $137,335 a year.

The report used a variation of Pew Research's definition of a middle class household, stating the salary range is "two-thirds to double the median U.S. salary." To determine income limits, the report analyzed data from the Census Bureau's 2022 one-year American Community Survey. New to the 2024 report, SmartAsset widened its analysis of income data from 100 to 345 of the largest American cities.

The Woodlands' middle class income thresholds are egregiously higher than the national average, the study found.

"In a large U.S. city, a middle-class income averages between $52,000 and $155,000," the report says. "The median household income across all 345 cities is $77,345, making middle-class income limits fall between $51,558 and $154,590."

Sugar Land was right behind The Woodlands, ranking No. 13 out of all 345 U.S. cities, with households needing to make between $88,502 and $265,532 a year to maintain their "middle class" status.

In a shocking turn of events, Houston plummeted into No. 254 this year after ranking among the top 100 in SmartAsset's 2023 report. At the time, a Houston household needed to make between $37,184 and $110,998 a year to be considered middle class. But the latest findings from the 2024 report show the necessary salary range to maintain a middle class designation in Houston is now between $40,280 and $120,852 a year.

The study's findings are shedding light on further growing financial stress and affordability struggles throughout the U.S., likely heightened by inflation and cost of living increases.

"As a middle-class American, there is some expectation for living a lifestyle of relative comfort," the report said. "But as costs have increased significantly over the last few years, the middle class is now feeling a squeeze in their finances."

Here’s what it takes to be middle class in other Houston-area cities:

  • No. 34 – Atascocita: between $71,748 and $215,266 a year
  • No. 39 – League City: between $69,904 and $209,734 a year
  • No. 45 – Pearland: between $69,990 and $206,992 a year
  • No. 211 – Conroe: between $43,814 and $131,456 a year
  • No. 273 – Pasadena: between $38,048 and $114,156 a year

Middle class income thresholds within the top 10 U.S. cities
The Woodlands wasn't the only Texas city to earn a spot in the top 10. Frisco, a suburb outside of Dallas, ranked two spots higher to claim No. 8 in the national comparison of U.S. cities with the highest income thresholds to be labeled middle class.

Middle class households in Frisco need to make between $97,266 and $291,828 a year, with the median household income at $145,914, according to the report.

Unsurprisingly, half of the top 10 cities with the highest middle class income ceilings are in California. The report found households in four of the five cities could be bringing in over $300,000 a year in income and still be classified as middle class.

California’s overall high cost-of-living means residents in the No. 1 city of Sunnyvale would need to make between $113,176 and $339,562 a year to be labeled middle class. Sunnyvale overtook Fremont for the top spot in the report in 2024.

The top 10 cities with the highest middle class ceilings are:

  • No. 1 – Sunnyvale, California
  • No. 2 – Fremont, California
  • No. 3 – San Mateo, California
  • No. 4 – Santa Clara, California
  • No. 5 – Bellevue, Washington
  • No. 6 – Highlands Ranch, Colorado
  • No. 7 – Carlsbad, California
  • No. 8 – Frisco, Texas
  • No. 9 – Naperville, Illinois
  • No. 10 – The Woodlands, Texas

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 explodes with 16 percent surge in population, new census data shows

Growth spurt

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.

Autonomous truck company rolls out driverless Houston-Dallas route

up and running

Houston is helping drive the evolution of self-driving freight trucks.

In October, Aurora opened a more than 90,000-square-foot terminal at a Fallbrook Drive logistics hub in northwest Houston to support the launch of its first “lane” for driverless trucks—a Houston-to-Dallas route on the Interstate 45 corridor. Aurora opened its Dallas-area terminal in April and the company began regular driverless customer deliveries between the two Texas cities on April 27.

Close to half of all truck freight in Texas moves along I-45 between Houston and Dallas.

“Now, we are the first company to successfully and safely operate a commercial driverless trucking service on public roads. Riding in the back seat for our inaugural trip was an honor of a lifetime – the Aurora Driver performed perfectly and it’s a moment I’ll never forget,” Chris Urmson, CEO and co-founder of Pittsburgh-based Aurora, said in a news release.

Aurora produces software that controls autonomous vehicles and is known for its flagship product, the Aurora Driver. The software is installed in Volvo and Paccar trucks, the latter of which includes brands like Kenworth and Peterbilt.

Aurora previously hauled more than 75 loads per week under the supervision of vehicle operators from Houston to Dallas and Fort Worth to El Paso for customers in its pilot project, including FedEx, Uber Freight and Werner. To date, it has completed over 1,200 miles without a driver.

The company launched its new Houston to Dallas route with customers Uber Freight and Hirschbach Motor Lines, which ran supervised commercial pilots with Aurora.

“Transforming an old school industry like trucking is never easy, but we can’t ignore the safety and efficiency benefits this technology can deliver. Autonomous trucks aren’t just going to help grow our business – they’re also going to give our drivers better lives by handling the lengthier and less desirable routes,” Richard Stocking, CEO of Hirschbach Motor Lines, added in the statement.

The company plans to expand its service to El Paso and Phoenix by the end of 2025.

“These new, autonomous semis on the I-45 corridor will efficiently move products, create jobs, and help make our roadways safer,” Gov. Greg Abbott added in the release. “Texas offers businesses the freedom to succeed, and the Aurora Driver will further spur economic growth and job creation in Texas. Together through innovation, we will build a stronger, more prosperous Texas for generations.”

In July, Aurora said it raised $820 million in capital to fuel its growth—growth that’s being accompanied by scrutiny.

In light of recent controversies surrounding self-driving vehicles, the International Brotherhood of Teamsters, whose union members include over-the-road truckers, recently sent a letter to Lt. Gov. Dan Patrick calling for a ban on autonomous vehicles in Texas.

“The Teamsters believe that a human operator is needed in every vehicle—and that goes beyond partisan politics,” the letter states. “State legislators have a solemn duty in this matter to keep dangerous autonomous vehicles off our streets and keep Texans safe. Autonomous vehicles are not ready for prime time, and we urge you to act before someone in our community gets killed.”

Houston cell therapy company launches second-phase clinical trial

fighting cancer

A Houston cell therapy company has dosed its first patient in a Phase 2 clinical trial. March Biosciences is testing the efficacy of MB-105, a CD5-targeted CAR-T cell therapy for patients with relapsed or refractory CD5-positive T-cell lymphoma.

Last year, InnovationMap reported that March Biosciences had closed its series A with a $28.4 million raise. Now, the company, co-founded by Sarah Hein, Max Mamonkin and Malcolm Brenner, is ready to enroll a total of 46 patients in its study of people with difficult-to-treat cancer.

The trial will be conducted at cancer centers around the United States, but the first dose took place locally, at The University of Texas MD Anderson Cancer Center. Dr. Swaminathan P. Iyer, a professor in the department of lymphoma/myeloma at MD Anderson, is leading the trial.

“This represents a significant milestone in advancing MB-105 as a potential treatment option for patients with T-cell lymphoma who currently face extremely limited therapeutic choices,” Hein, who serves as CEO, says. “CAR-T therapies have revolutionized the treatment of B-cell lymphomas and leukemias but have not successfully addressed the rarer T-cell lymphomas and leukemias. We are optimistic that this larger trial will further validate MB-105's potential to address the critical unmet needs of these patients and look forward to reporting our first clinical readouts.”

The Phase 1 trial showed promise for MB-105 in terms of both safety and efficacy. That means that potentially concerning side effects, including neurological events and cytokine release above grade 3, were not observed. Those results were published last year, noting lasting remissions.

In January 2025, MB-105 won an orphan drug designation from the FDA. That results in seven years of market exclusivity if the drug is approved, as well as development incentives along the way.

The trial is enrolling its single-arm, two-stage study on ClinicalTrials.gov. For patients with stubborn blood cancers, the drug is providing new hope.

Elon Musk's SpaceX site officially becomes the city of Starbase, Texas

Starbase, Texas

The South Texas home of Elon Musk’s SpaceX rocket company is now an official city with a galactic name: Starbase.

A vote Saturday, May 3, to formally organize Starbase as a city was approved by a lopsided margin among the small group of voters who live there and are mostly Musk’s employees at SpaceX. With all the votes in, the tally was 212 in favor to 6 against, according to results published online by the Cameron County Elections Department.

Musk celebrated in a post on his social platform, X, saying it is “now a real city!”

Starbase is the facility and launch site for the SpaceX rocket program that is under contract with the Department of Defense and NASA that hopes to send astronauts back to the moon and someday to Mars.

Musk first floated the idea of Starbase in 2021 and approval of the new city was all but certain. Of the 283 eligible voters in the area, most are believed to be Starbase workers.

The election victory was personal for Musk. The billionaire’s popularity has diminished since he became the chain-saw-wielding public face of President Donald Trump’s federal job and spending cuts, and profits at his Tesla car company have plummeted.

SpaceX has generally drawn widespread support from local officials for its jobs and investment in the area.

But the creation of an official company town has also drawn critics who worry it will expand Musk’s personal control over the area, with potential authority to close a popular beach and state park for launches.

Companion efforts to the city vote include bills in the state Legislature to shift that authority from the county to the new town’s mayor and city council.

All these measures come as SpaceX is asking federal authorities for permission to increase the number of South Texas launches from five to 25 a year.

The city at the southern tip of Texas near the Mexico border is only about 1.5 square miles (3.9 square kilometers), crisscrossed by a few roads and dappled with airstream trailers and modest midcentury homes.

SpaceX officials have said little about exactly why they want a company town and did not respond to emailed requests for comment.

“We need the ability to grow Starbase as a community,” Starbase General Manager Kathryn Lueders wrote to local officials in 2024 with the request to get the city issue on the ballot.

The letter said the company already manages roads and utilities, as well as “the provisions of schooling and medical care” for those living on the property.

SpaceX officials have told lawmakers that granting the city authority to close the beach would streamline launch operations. SpaceX rocket launches and engine tests, and even just moving certain equipment around the launch base, requires the closure of a local highway and access to Boca Chica State Park and Boca Chica Beach.

Critics say beach closure authority should stay with the county government, which represents a broader population that uses the beach and park. Cameron County Judge Eddie Trevino, Jr. has said the county has worked well with SpaceX and there is no need for change.

Another proposed bill would make it a Class B misdemeanor with up to 180 days in jail if someone doesn’t comply with an order to evacuate the beach.

The South Texas Environmental Justice Network, which has organized protests against the city vote and the beach access issue, held another demonstration Saturday that attracted dozens of people.

Josette Hinojosa, whose young daughter was building a sandcastle nearby, said she was taking part to try to ensure continued access to a beach her family has enjoyed for generations.

With SpaceX, Hinojosa said, “Some days it’s closed, and some days you get turned away."

Organizer Christopher Basaldú, a member of the Carrizo/Comecrudo Nation of Texas tribe, said his ancestors have long been in the area, where the Rio Grande meets the Gulf.

“It’s not just important,” he said, “it’s sacred.”
