State demographer: Wayzata enrollment growth to slow; high school could add about 1,000 students over 10 years

Hazel Reinhart, state demographer, told the Wayzata Public Schools Board of Education at a May 27 work session that long-term trends — lower fertility, fewer births and different housing types — mean the district’s rapid enrollment growth is likely to slow even as some grades, especially high school, could continue to expand in the next decade.

Reinhart said Minnesota’s total fertility rate was 1.73 in 2023 (replacement is 2.11; the U.S. rate was about 1.62), and that decline in births is already feeding through to smaller kindergarten cohorts. “We now have born the children who will be kindergarteners in 2029–30,” she told board members, noting the size of that birth pool has decreased and therefore the district’s kindergarten “capture rate” would need to rise meaningfully to sustain past growth.

The projections matter because they change the district’s planning horizon. Reinhart used a cohort-survival method and two capture-rate assumptions (a recent low and a higher scenario) and said the result is slower districtwide growth over the next 10 years than Wayzata saw in the prior decade. At the same time, she cautioned that different net migration assumptions change the mix: “The high migration assumption produces much more high school growth” and, speaking of potential scale, she said the high school “estimate could be a thousand students larger than it is today in 10 years.”

Why it matters: Wayzata grew nearly 20 percent — roughly 2,000 students — over the past 10 years, largely from resident growth rather than open enrollment. Board and staff use enrollment projections to set boundaries, plan facilities and budget for staffing and construction. Reinhart warned that elementary declines typically precede overall plateaus and that the district should plan for shifting demand across individual schools.

Key findings and context

- Fertility and births: Reinhart pointed to lower fertility statewide and fewer births as a core driver of smaller future kindergarten cohorts. She showed statewide and Hennepin County birth declines since 2008 and noted suburban Hennepin County births fell less than Minneapolis or the state overall.

- Past growth sources: Wayzata’s growth in the prior decade was unusually driven by resident births and housing rather than open enrollment; only about 1.8 percent of Wayzata students were nonresidents, she said.

- Competition: Nonpublic schools enroll more Wayzata-area students than other public options and remain a significant competitive factor for kindergarten capture.

- Net migration and year-to-year variation: Reinhart called the district’s recent net in-migration “robust” (she identified a roughly 300–340 net in-migration figure averaged across recent years), but warned much of a single recent annual net inflow was concentrated in a single grade transition and might not be sustained.

- Housing and yields: Using national and regional experience, Reinhart presented yield assumptions she applied to recent and proposed housing: single-family detached units (assumed yield 0.6 students per unit for projections), townhomes (about 0.22), and apartments (about 0.11–0.15). She reported 2020–2024 housing completions in the district period of about 1,449 single-family detached units, 376 townhomes, 106 apartment units and 38 condos. Planned but not approved projects in parts of Plymouth could add hundreds of single-family units and many apartments; those remain uncertain and were not counted as approved in her baseline projections.

- School-level differences: Reinhart’s school-by-school rollups show the largest projected elementary decreases at Gleason Lake and Greenwood (because large older cohorts will age out) and the largest elementary increase at Meadow Ridge. She flagged that middle-school projections were less certain and that recent boundary changes make school-level forecasts sensitive to assumptions.

Board discussion and questions

Board members pressed Reinhart on assumptions about yields from new housing and the effect of recent one-year enrollment anomalies. Superintendent Dr. Chase Anderson confirmed a single-year window of open enrollment for ninth- and tenth-graders increased ninth-grade enrollment by roughly 65–70 students this year and has since been closed. Board members asked about local redevelopment, potential new roads and timing of large projects in Plymouth and Medina; Reinhart said she treats only projects already on paper as likely to affect the next five years and called Medina a “wild card.”

What was not decided

No formal actions or votes were taken at the work session. Reinhart’s analysis was presented for the board’s information and for use in boundary and facilities planning; she offered to refine middle-school projections and to revisit particular assumptions if the board requests further study.

Ending

Reinhart told the board she would be available for follow-up work and reiterated the principal planning implications: declining kindergarten pools nationwide and locally require the district to track births, housing type and migration closely; the district may face a plateau in total enrollment while demand shifts among grade bands and individual schools.
