Chandler Unified consultants point to aging households, falling births and ESA use as drivers of multi‑year enrollment declines

Applied Economics consultant Rick Brammer told the Chandler Unified governing board on Oct. 22 that the district’s long run enrollment picture has shifted from rapid growth in the 2000s to a protracted decline driven mainly by demographic change and by the introduction of new school‑choice options.

Brammer, who has prepared district enrollment studies for more than three decades, presented 25 years of 40th‑day headcount data and a pair of forecasting models — a regional (top‑down) model and a detailed, parcel‑level (bottom‑up) grid model. He said Chandler’s total population has continued to grow but the share aged 0–18 has fallen and the cohort sizes that feed elementary grades are now much smaller than the high‑school cohorts that followed them.

“Many of the factors stacked up against enrollment are demographic — aging householders, lower birth rates — and the ESA program has added another new pathway out of district schools,” Brammer said. He added that while charter school growth contributed to earlier shifts, the most recent declines are less about charters and more about the ESA program and the shape of the local birth cohort curve.

Applied Economics showed maps of the district’s quarter‑section grids demonstrating broad declines in student counts across most of the district. Don Graves, the consultants’ residential‑development lead, described several active and imminent projects (Waterston, Legado, a Lennar/Harvest Grove parcel, Zinke properties) concentrated in the eastern and southeastern halves of the district and along freeway and arterial corridors. Graves said Chandler is maturing as a housing market and most future housing will be multifamily, though ongoing single‑family phases will add several thousand housing units over the coming decade.

The consultants stressed two implications for planning: first, enrollment declines will likely continue in the coming five to 10 years under current patterns; second, localized redevelopment and new housing will produce pockets of growth that may moderate losses at individual schools. They presented scenarios in which a stabilized in‑district service rate would limit next‑year losses to a few hundred students, while the recent steep decline trajectory would imply larger drops.

Board members pressed the consultants on housing generation rates and the likely student yield from different product types. Brammer and Graves said generation varies sharply by product and price: high‑cost urban apartments can produce near‑zero students per unit, affordable multifamily can generate about 0.2 students per unit, and new single‑family typically yields roughly 0.6–0.7 students per unit. They recommended using disaggregated product categories (several multifamily types and multiple single‑family product lines) rather than a single per‑unit assumption when forecasting school impacts.

The presentation concluded with a summary: Chandler remains a large, high‑service district with approximately 40,000 students, and it is likely to see further enrollment declines over the next decade without an offsetting demographic reversal. The board and staff said they will use the consultants’ grid maps and scenario work to support staffing decisions, boundary considerations and the capital plan.

Ending: The consultants’ full slide set and suggested short‑ and mid‑term scenarios will be used by district staff as they meet with principal and staffing committees and as the board considers implications for the capital plan and long‑range staffing.
