Estimated births fell by as much as 30% between 2014 and 2024 across several of Houston's largest school districts, including Aldine, Alief, Houston, Pasadena, Deer Park, Galena Park and Stafford, even as the region kept adding new residents overall. Montgomery County told a different story over the same stretch, with its largest districts posting birth increases of up to 67%. The split points to a region where population growth is increasingly driven by people moving in rather than babies being born.
A Decade of Fewer Babies in Core Houston Districts
According to a Kinder Institute for Urban Research analysis, the estimated number of births declined 15% to 30% in Aldine, Alief, Deer Park, Galena Park, Houston, Pasadena and Stafford school districts between 2014 and 2024. The same report found that births within Aldine and Houston ISDs specifically fell by more than 10% between 2010 and 2020. Those declines have shown up in classrooms too: Aldine, Alief, Houston, Galveston, Pasadena and Texas City ISDs all saw enrollment drop by 9% to 16% between the 2019-20 and 2024-25 school years, per the same report.
The ripple effects stretch from maternity wards to kindergarten rosters. For every 100 babies born in Alief ISD in the 2018-19 school year, only about 51 kindergartners ultimately enrolled in the district for 2023-24, the Kinder Institute found — a gap that reflects both fewer births and families moving elsewhere before their kids reach school age. Districts south of Houston saw similar patterns, with estimated birth totals falling 27% in Galveston, 19% in Pearland, 15% in Brazosport and 12% in Clear Creek school districts over the 2014-2024 period.
Montgomery County Grows While Harris County Lags
Not every corner of the region is shrinking its youngest ranks. Births jumped by 17% to 67% in Montgomery County's largest districts — Conroe, Magnolia, Montgomery, New Caney and Splendora ISDs — according to the Kinder Institute's analysis. Birth counts and in-migration have spiked on Houston's north side and in exurban communities built around large, less-expensive housing developments, the same report notes.
Population growth overall is still happening, just unevenly. Greater Houston added an estimated 126,720 people between mid-2024 and mid-2025, though that was a slowdown from the prior year's 190,261, the Kinder Institute reported in a separate analysis. Harris County itself grew by about 1% in that span, adding nearly 50,000 people but trailing every other county in the metro area, while the nine other Houston-area counties combined gained roughly 78,000 people, a 2.8% increase. The institute framed it simply: Greater Houston is still growing at a healthy clip, even with birth rates flattening, domestic migration slowing and immigration policies changing.
Money Worries Top the List of Reasons Families Cite
Affordability concerns loom large in national survey data cited alongside the local trends. More than 70% of Americans said raising children was unaffordable in the 2025 American Family Survey, according to Brigham Young University's social sciences program — a 20-point jump over the past decade. Insufficient money was the single most-cited barrier to having children, named by 43% of respondents in that survey.
Harris County's Fertility Rate Had One Up Year
The longer-term decline hasn't been perfectly linear everywhere. Harris County's fertility rate actually rose 2.88% in 2022 after nearly a decade of steady decline that began in 2015, per Community Impact. The biggest jump came among women ages 40 to 44, whose fertility rate climbed 8.91% that year, the outlet reported.
Regional planners are watching these shifts closely. The Houston-Galveston Area Council says its population projections lean on historical trends in migration, fertility and survival rates, though the agency cautions that those forecasts may not fully capture the impact of future policy changes, sudden economic shifts, environmental factors or technological advancements, according to its own regional growth forecast. Whether Montgomery County's surge or Harris County's slower growth becomes the dominant pattern for the region may hinge on exactly those unpredictable variables.
