Minooka CHSD 111 projects enrollment declines over five years; kindergarten cohorts flagged

District administrators presented multi‑year enrollment projections that show declining student populations over the next five years and raised planning implications for staffing and facilities.

Using a three‑year cohort survival method and September’s official counts, administrators reported Manuka High current enrollment at about 3,949 students, projected to fall to roughly 3,655 by 2031 — about a 9% decrease in the five‑year window. Districtwide September enrollment was reported around 2,888 and was projected to decline to about 2,715 by 2031.

Administrators said the calculations use feeder district cohorts, a three‑year average for kindergarten, and September counts that are submitted to the state. They noted wider demographic trends in Illinois — including a roughly 25% drop in birth rates since 2008 and persistent net out‑migration from the state — as contributing factors. Comments at the meeting underscored how local housing development patterns could alter projections; administrators said some Shorewood and local developments may provide limited backfill but cautioned the district’s historic methodologies are being disrupted by changing housing and demographic patterns.

The presentation emphasized that while the district has physical room for additional students in the near term, sustained declines could influence staffing and capital planning. Trustees asked for further details about unit yields from housing developments and the percentage of new units typically translating into district students (staff cited a historical conversion rate on single‑family homes of roughly 0.08–0.25 students per household depending on product type and year). Administrators committed to annual updates so the board can monitor trends and align future construction or renovation timing with enrollment realities.

The board received the projections as information; no policy changes were adopted at the meeting.
