SOUTH PADRE ISLAND, Texas — Over the past half-century, the Rio Grande Valley has experienced a dramatic demographic explosion and a fundamental economic pivot—evolving from an agricultural and border-retail economy into a regional health, education, and energy corridor.
However, despite rapid population growth and emerging high-tech and industrial sectors, the region continues to wrestle with deep-seated structural challenges: significant gaps in higher education attainment, low labor force participation, and per-capita income levels that remain at just half the national average.
That was the central message delivered by Dr. Yu Liu, associate professor of finance at the University of Texas Rio Grande Valley (UTRGV) School of Economics and Finance, during a presentation at "The State of the Regional Workforce Conference."
The event, co-hosted by Workforce Solutions Lower Rio Grande Valley and Workforce Solutions Cameron, aimed to establish a comprehensive historical perspective on the RGV labor force to inform regional strategy regarding economic opportunities, industrial shifts, and future workforce development.
Tracing the region’s economic arc from the 1970s to the present, Liu highlighted the sheer scale of the Valley’s expansion across its four core counties: Hidalgo, Cameron, Starr, and Willacy.
"In total, we have 1.44 million residents in four counties together," Liu said, noting that the regional population has nearly quadrupled since 1970, consistently outstripping statewide growth rates for decades.
Beyond raw numbers, Liu stressed that the RGV possesses a distinct demographic advantage: a remarkably young population. Nearly 28% of Valley residents are under the age of 18, compared to 24% statewide in Texas and 21% nationally.
Employment figures reflect a parallel shift. The McAllen and Brownsville metropolitan areas now account for approximately 467,000 payroll jobs—roughly 2.6 times the total recorded in the 1990s.
However, Liu cautioned that demographic expansion has created a clear divergence between population size and economic metrics:
"In terms of per capita personal income, we are 50% relative to the U.S.," Liu said. "We have these three gaps here: the education gap, the income gap, and the labor force participation gap."
Liu detailed how the Valley’s underlying employment pillars shifted over the last four decades.
Historically rooted in agriculture, citrus, winter vegetables, and commercial fishing, the region suffered severe systemic shocks during back-to-back hard freezes in December 1983 and 1989, which devastated citrus groves and forced labor market shifts away from seasonal farm work.
Simultaneously, while cross-border retail, the Maquiladora program, and NAFTA established the Valley as a premier international logistics corridor, much of the trade flow passed through without capturing local value-add processing.
Today, healthcare and education have become the dominant economic drivers. While accounting for roughly one in every ten jobs in the 1990s, the sector now represents nearly one out of every three jobs in the region—driven in part by institutions like UTRGV.
Looking toward future growth engines, Liu pointed to major heavy-industrial, aerospace, and energy investments concentrated around the Port of Brownsville, including NextDecade’s Rio Grande LNG project and SpaceX’s Starbase facility at Boca Chica.
"We actually see with our eyes LNG building there... we see the big rocket ship there. That’s all wonderful. We know they are hiring," Liu said, adding that the Port of Brownsville directly and indirectly anchors nearly 10,000 regional jobs.
To capitalize on incoming industrial capital and narrow income disparities, Liu outlined several actionable priorities for regional leadership and workforce boards:
"We try to act as one region, not just a lower region. Together, we are one region," Liu emphasized.
Addressing emerging technological shifts, Liu concluded by pointing to the rapid integration of artificial intelligence across industries, calling on regional educational institutions and employers to proactively integrate AI training into workforce development programs.
"AI is something, whether you like it or not, it's here," Liu said. "Whether it's a threat or an opportunity, we have to welcome it. We need to figure out ways to make it benefit our economy."
