Demographer projects modest enrollment decline at Glen Rock elementary and middle schools

The board heard a demographic study from Dr. David Greer (demographer/consultant, Statistical Forecasting) that projects a modest overall enrollment decline in the next five years driven by falling elementary and middle-school cohorts and mixed housing turnover signals.

Nut graf: Dr. Greer presented two projection scenarios and an independent housing-turnover analysis. Both methods showed falling elementary enrollment and a net district decline over five years, though the magnitude varies by method and assumptions about new housing.

Dr. Greer summarized the methods and data: historical October enrollment counts, birth trends, cohort-survivor (grade progression) ratios approved by the state Department of Education, local planning/zoning development lists and a housing turnover model developed by Berkeley authors and Rutgers yield multipliers. He said the district's October enrollment (the year-to-date count used in projections) was reported in the presentation as roughly in the 2,500-range and that recent years show inward migration in many grades but lower birth counts and a gap in the 20s-30s age cohort in borough population pyramids.

Projection results: using different averaging windows for grade-progression ratios, the consultant presented two five-year scenarios: a larger decline (about 77 students districtwide) and a smaller decline (about 19 students). Dr. Greer adjusted projections to add expected yield from a planned Rock Road development of 69 housing units; he used Rutgers multipliers and reported that the development would be expected to generate about 27 students under those statewide multipliers.

Capacity: The study compared projected enrollments with building capacities at the grade-configuration level (K-5, 6-8, 9-12). Dr. Greer reported a current elementary-seat shortage of about 42 seats against capacity (the analysis aggregated building capacity by configuration), while middle- and high-school capacity showed larger surpluses; overall the district does not face an immediate, large space shortfall under the projection scenarios.

Trustees and residents asked technical questions about assumptions: Ms. Pearlamus asked why median house values in the American Community Survey (quoted at about $786,000) differ from local assessor values (quoted at about $591,000), and Dr. Greer explained ACS sampling and confidence-interval issues. Trustee Michael Cohen questioned the Rutgers multipliers and how well they fit Glen Rock; Dr. Greer said the multipliers are widely used and include confidence intervals, but local context can alter yields.

Ending: Dr. Greer told the board the district's enrollment is likely to decline modestly over five years but emphasized sensitivity to housing market changes and turnover rates. The board received the study for planning; no vote or policy change was taken during the presentation.
