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)

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

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 with Houston routes goes public

on a roll

Kodiak Robotics, a provider of AI-powered autonomous vehicle technology, has gone public through a SPAC merger and has rebranded as Kodiak AI. The company operates trucking routes to and from Houston, which has served as a launchpad for the business.

Privately held Kodiak, founded in 2018, merged with a special purpose acquisition company — publicly held Ares Acquisition Corp. II — to form Kodiak AI, whose stock now trades on the Nasdaq market.

In September, Mountain View, California-based Kodiak and New York City-based Ares disclosed a $145 million PIPE (private investment in public equity) investment from institutional investors to support the business combo. Since announcing the SPAC deal, more than $220 million has been raised for the new Kodiak.

“We believe these additional investments underscore our investors’ confidence in the value proposition of Kodiak’s safe and commercially deployed autonomous technology,” Don Burnette, founder and CEO of Kodiak, said in a news release.

“We look forward to leading the advancement of the commercial trucking and public sector industries,” he added, “and delivering on the exciting value creation opportunities ahead to the benefit of customers and shareholders.”

Last December, Kodiak debuted a facility near George Bush Intercontinental/Houston Airport for loading and loading driverless trucks. Transportation and logistics company Ryder operates the “truckport” for Ryder.

The facility serves freight routes to and from Houston, Dallas and Oklahoma City. Kodiak’s trucks currently operate with or without drivers. Kodiak’s inaugural route launched in 2024 between Houston and Dallas.

One of the companies using Kodiak’s technology is Austin-based Atlas Energy Solutions, which owns and operates four driverless trucks equipped with Kodiak’s driver-as-a-service technology. The trucks pick up fracking sand from Atlas’ Dune Express, a 42-mile conveyor system that carries sand from Atlas’ mine to sites near customers’ oil wells in the Permian Basin.

Altogether, Atlas has ordered 100 trucks that will run on Kodiak’s autonomous technology in an effort to automate Atlas’ supply chain.

Rice University scientists invent new algorithm to fight Alzheimer's

A Seismic Breakthrough

A new breakthrough from researchers at Rice University could unlock the genetic components that determine several human diseases such as Parkinson's and Alzheimer's.

Alzheimer's disease affected 57 million people worldwide in 2021, and cases in the United States are expected to double in the next couple of decades. Despite its prevalence and widespread attention of the condition, the full mechanisms are still poorly understood. One hurdle has been identifying which brain cells are linked to the disease.

For years, it was thought that the cells most linked with Alzheimer's pathology via DNA evidence were microglia, infection-fighting cells in the brain. However, this did not match with actual studies of Alzheimer's patients' brains. It's the memory-making cells in the human brain that are implicated in the pathology.

To prove this link, researchers at Rice, alongside Boston University, developed a computational algorithm called “Single-cell Expression Integration System for Mapping Genetically Implicated Cell Types," or SEISMIC. It allows researchers to zero in on specific neurons linked to Alzheimer's, the first of its kind. Qiliang Lai, a Rice doctoral student and the lead author of a paper on the discovery published in Nature Communications, believes that this is an important step in the fight against Alzheimer's.

“As we age, some brain cells naturally slow down, but in dementia — a memory-loss disease — specific brain cells actually die and can’t be replaced,” said Lai. “The fact that it is memory-making brain cells dying and not infection-fighting brain cells raises this confusing puzzle where DNA evidence and brain evidence don’t match up.”

Studying Alzheimer's has been hampered by the limitations of computational analysis. Genome-wide association studies (GWAS) and single-cell RNA sequencing (scRNA-seq) map small differences in the DNA of Alzheimer's patients. The genetic signal in these studies would often over-emphasize the presence of infection fighting cells, essentially making the activity of those cells too "loud" statistically to identify other factors. Combined with greater specificity in brain regional activity, SEISMIC reduces the data chatter to grant a clearer picture of the genetic component of Alzheimer's.

“We built our SEISMIC algorithm to analyze genetic information and match it precisely to specific types of brain cells,” Lai said. “This enables us to create a more detailed picture of which cell types are affected by which genetic programs.”

Though the algorithm is not in and of itself likely to lead to a cure or treatment for Alzheimer's any time soon, the researchers say that SEISMIC is already performing significantly better than existing tools at identifying important disease-relevant cellular signals more clearly.

“We think this work could help reconcile some contradicting patterns in the data pertaining to Alzheimer’s research,” said Vicky Yao, assistant professor of computer science and a member of the Ken Kennedy Institute at Rice. “Beyond that, the method will likely be broadly valuable to help us better understand which cell types are relevant in different complex diseases.”

Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its second Houston cohort this summer.

This year, the incubator grew to include its largest number of concurrent supported fellows, with 88 companies currently being supported nationally. In total, Activate has supported 296 fellows who have created 236 companies. Those companies have raised over $4 billion in follow-on funding, according to Activate. In Houston, it has supported several Innovation Awards finalists, including Solidec, Bairitone Health and Deep Anchor Solutions. It is led locally by Houston Managing Director Jeremy Pitts.

EnergyTech Nexus

Cleantech startup hub EnergyTech Nexus' mission is to accelerate the energy transition by connecting founders, investors and industrial stakeholders and helping to develop transformative companies, known as "thunderlizards."

The hub was founded in 2023 by CEO Jason Ethier, Juliana Garaizar and Nada Ahmed. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, EarthEn Energy and Solidec—many of which are current or past Innovation Awards finalists. This year Energy Tech Nexus launched its COPILOT Accelerator, powered by Wells Fargo Innovation Incubator (IN²) at the National Renewable Energy Laboratory (NREL). COPILOT partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. Energy Tech Nexus also launched its Liftoff fundraising program, its Investor Program, and a "strategic ecosystem partnership" with Greentown Labs.

Greentown Labs

Climatetech incubator Greentown Labs offers its community resources and a network to climate and energy innovation startups looking to grow.
