Demographer: Westfield schools need about 1,500–1,700 annual home turnovers to stabilize enrollment

Summary
At a joint city–school session, demographer Dr. Jerry McKibben warned that a persistent deficit of preschool‑age children means Westfield will need substantially more home sales or new construction each year—McKibben put a conservative target at about 1,500 homes and a realistic target at about 1,700—to avoid long‑term enrollment decline.
At a joint meeting of city and school leaders, demographer Dr. Jerry McKibben told officials that Westfield’s schools face a persistent shortfall in preschool‑age children that must be filled before elementary enrollment can grow.
McKibben, who said his office builds population forecasts from census data, local building permits and address‑level housing information, distinguished his two‑step forecasting approach from simpler projections: "A forecast is different. It's a 2 step procedure... The results of that population forecast drives the enrollment forecast." He told the room the model assumes several key variables including net transfers and housing market turnover.
One central assumption in the district’s forecast, McKibben said, was "we assume... negative 600 transfer students annually over the next 10 years." He added that the newly released 2025 fall transfer numbers (which he cited as 673) weaken that assumption and could change outcomes.
Explaining the district’s age structure, McKibben pointed to a sustained "0 to 4" cohort deficit and described how filling that preschool deficit is a prerequisite to long‑term enrollment growth. "You need about 900 between now and 2030 just to break even," he said referring to the gap created since 2020.
Pressed on how many housing market movements would be required to stabilize enrollment, McKibben gave two yardsticks: "God. I'm conservatively, I'd say 1,500. More realistic, I'd say 1,700." He said that figure is a combination of existing home sales and new construction and that distribution matters: if empty‑nester households are concentrated in different parts of the district than new building, redistricting or other distribution questions can follow.
City leaders said they will monitor building permits and home sales closely. Mayor Willis noted that the city had intentionally slowed approvals in recent years and that last year’s figures—about 854 existing‑home sales and roughly 752 new single‑family permits—fall short of the levels McKibben identified as necessary to maintain stable enrollment.
Both sides emphasized the need for continued data sharing. The superintendent and mayor proposed annual demographer briefings and a standing task force to coordinate planning for boundaries, facilities and infrastructure so that school construction and city growth proceed with aligned expectations.
The meeting concluded with officials saying they would watch spring and summer home‑sale activity and census updates before considering any policy changes.
