In the late 1800s through the mid-1950s, New York City's Ellis Island — sitting in the Statue of Liberty's shadow — served as the entry point for millions of new arrivals to the U.S.

Houston doesn't have its own version of Ellis Island, but perhaps it deserves a symbolic one to commemorate the flood of new arrivals from other states.

In 2017, Harris County welcomed more new out-of-state arrivals (81,781) than any other county in Texas, according to a data analysis released December 9 by StorageCafé, a self-storage marketplace.

That influx stands to reason, since Harris County is the state's largest county as measured by population (more than 4 million and counting). Still, it's astounding that Harris County attracted almost as many new arrivals as the entire population of Conroe (87,654 in 2018).

StorageCafé based its analysis on data published last year by the U.S. Census Bureau. The analysis excludes new arrivals from other Texas counties and new arrivals from outside the U.S.

No other county in the Houston metro area appeared in StorageCafé's ranking of the top 10 Texas counties for new arrivals from out of state. That hardly discounts the fact that the entire metro area is witnessing substantial population growth, though.

The Houston area added nearly 1.08 million residents between 2010 and 2018, growing at a rate of 18.2 percent, according to Census Bureau figures cited by the Greater Houston Partnership. From 2017 to 2018 alone, the region's population jumped by 91,689 — the third largest increase in the country — to just shy of 7 million.

To be clear, more than 1 million people didn't pack up and move to the Houston area from 2010 to 2018. Rather, the region's population growth rate comprises arrivals and births stacked up against departures and deaths.

Although the StorageCafé analysis indicates a Texas-leading population spike, Bill Fulton, director of Rice University's Kinder Institute for Urban Research, notes that Harris County has experienced an overall decline in population growth since 2015.

"This is not surprising given the drop in oil prices, which led to economic stagnation in Houston," Fulton tells CultureMap.

Fulton points out that Harris County's population gains don't match the combined growth of the Dallas-Fort Worth area's two biggest counties — Dallas and Tarrant. Dallas County has about 2.6 million residents, while Tarrant County (Fort Worth) has a little over 2 million. That's a total of about 4.6 million, compared with Harris County's nearly 4.7 million residents.

"Don't be deceived into thinking that because Harris County has a much greater population increase than any other county, that, therefore, metro Houston is growing a lot faster than DFW," Fulton says. "If you add the Dallas and Tarrant numbers together, it clearly shows that DFW is still attracting more [newcomers] than Houston."

"The bottom line is: For the past several years, DFW has been growing faster than Houston, and that growth has been driven by [more newcomers] from other states," Fulton adds.

Indeed, grabbing second place in the StorageCafé ranking was Dallas County, with 47,336 new out-of-state arrivals in 2017. And in the No. 3 spot, next-door Tarrant County picked up 44,181 new arrivals. That means Dallas and Tarrant counties drew more than 91,500 new out-of-state residents in 2017, beating the total for Harris County.

Two other DFW counties, Collin and Denton, ranked sixth and seventh, respectively, in StorageCafé's list of the top 10 Texas counties. Collin County saw 24,918 new out-of-state arrivals in 2017, with Denton County at 22,190.

All told, the four DFW counties in Texas' top 10 absorbed 138,625 new out-of-state residents in 2017. By comparison, 138,541 people lived in Denton in 2018, the Census Bureau says.

From 2010 to 2018, Dallas-Fort Worth added more residents — over 1.11 million, or a growth rate of 17.3 percent — than any other major metro area in the country, according to the Census Bureau. In terms of the sheer number of new residents, DFW eclipsed Houston during that period, but Houston held a slight edge for percentage growth.

Bexar County, which anchors the San Antonio metro area, claimed the No. 4 spot in the StorageCafé ranking, attracting 41,062 out-of-state newcomers in 2017.

Just behind it, at No. 5, was Travis County, which anchors the Austin metro area. The StorageCafé data shows 33,939 people relocated to Travis County from out of state in 2017. Rounding out the top 10 was Williamson County (suburban Austin), with 15,712 out-of-state newcomers.

Combined, Travis and Williamson counties gained close to 50,000 out-of-staters in 2017. By comparison, Pflugerville was home to 59,245 residents in 2018, according to the Census Bureau.

Others in the top 10 were El Paso County at No. 8 and Bell County (home of Killeen and Temple) at No. 9.

UTHealth Houston officially opens new tower in TMC's Helix Park

open for innovation

UTHealth Houston School of Public Health recently opened its new state-of-the-art tower in the Texas Medical Center’s Helix Park.

The 350,000-square-foot, 10-story campus at 1930 Old Spanish Trail was celebrated with an official ribbon-cutting ceremony on Oct. 28. The $229 million project will consolidate all UTHealth Houston School of Public Health operations into one facility. It will also connect students who are at the Austin, Brownsville, Dallas, El Paso and San Antonio campuses with peers and faculty through digital and distance learning.

Disciplines taught in the new tower will include epidemiology, genetics, nutrition, health policy, data science and health promotion, UTHealth shared when the building first broke ground in 2023.

Architects Kirksey Architecture and Smith Group designed the building, and Vaughn Construction served as general contractor. The facility features labs for studying human disease, classrooms and spaces to support interdisciplinary and community-based research, a broadcast studio and a teaching kitchen. A skybridge over Old Spanish Trail connects the new tower with a plaza that's shared with MD Anderson.

“This new facility reflects the kind of forward-looking investment that will serve Texans for generations,” Janiece Longoria, vice chairman of the UT System Board of Regents, said in a news release. “By creating an environment where talented people can learn, collaborate, and pursue new ideas, UTHealth Houston is building capacity to meet the challenges of tomorrow while strengthening its impact across our state.”

UTHealth says the system aims for the new campus to expand on collaborative research efforts and continue graduate education, as enrollment at the School of Public Health has increased by 27 percent over the last five years.

“This new building, with its state-of-the-art education technology and learning environment, will strengthen and advance the school’s mission to educate and train the next generation of experts who will advance scientific discovery, shape evidence-based health policy, and lead innovative solutions to the complex health challenges in communities throughout Texas and across the nation,” Kevin Morano, senior vice president, provost and chief academic officer of UTHealth Houston, added in a news release.

Attending the ceremony were Dr. Melina R. Kibbe, UTHealth Houston president and Alkek Williams Distinguished Chair; Eric Boerwinkle, dean, M. David Low Chair in Public Health and Kozmetsky Family Chair in Human Genetics at the School of Public Health; Texas State Representative Lauren Ashley Simmons, Texas House District 146; representatives of the offices of Senator John Cornyn and Harris County Commissioner Rodney Ellis; and Dr. Theresa Tran, director of the Houston Health Department.

"This building represents far more than a home for our school,” Boerwinkle added in the release. “It represents the people who make our mission possible: the faculty, staff, and students who fill each laboratory and classroom with curiosity, discovery, and purpose to improve the population’s quality of life.”

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.
