PASA demographic forecast: Alvin ISD projects continued growth, elementary overcrowding in next five years

Consultants from Population & Survey Analysts (PASA) presented a detailed 10‑year enrollment forecast to the Alvin ISD board on April 1, saying the district remains in a high‑growth phase driven primarily by new single‑family housing. The middle (most likely) scenario projects nearly 37,000 students in a decade, with roughly 3,100 new housing occupancies expected during the period.

PASA showed that births in the district over the past four years have trended up — a factor that typically increases kindergarten enrollment when those children reach school age — and noted that in-migration tied to new subdivisions (Meridiana, Peach Tree, Creek Haven, Massie Oaks) continues to add students. The firm said about 90% of projected new units are expected to be traditional single‑family construction and about 8% multifamily; multifamily developments have lower student yields.

Geocoded student-address maps and planning-unit heat maps indicate the strongest near‑term growth on the western side of the district (Highway 288 corridor and Manville/Iowa Colony) and increasing activity around Alvin linked to infrastructure and Grand Parkway extension work. PASA estimated districtwide student density averages about 0.55 enrolled Alvin ISD students per single‑family home, with Shadow Creek Ranch considerably higher and some newly platted subdivisions lower.

Capacity projections in the presentation flagged several elementary attendance zones (e.g., Mason, Barbara Bennett, Meridiana, Nichols Mock) approaching or exceeding 120% utilization within five years. PASA noted the district’s 2024 bond funded two elementary schools expected to open in 2027 to relieve some pressure; junior high and high school capacities were generally adequate in the near term but could need future attention (Iowa Colony HS projected ~128% utilization in year 10 under the middle scenario).

Trustees asked whether virtual programs, vouchers and charter openings could further change projections. PASA said the two Harmony charter campuses slated to open near the district in 2027 may draw a modest number of students, and that virtual enrollment has increased since COVID but is unlikely to replace in‑person schools as the primary competitor. PASA recommended continued monitoring of housing starts, student-per‑home ratios, and charter/virtual developments to refine projections.

The presentation provided planners and trustees with a staging timeline for capacity needs and will inform next steps for boundary planning, bond‑funded school openings and long-term facilities decisions.
