New York City’s traditional public schools shed about 22,000 students this year, the system’s steepest enrollment decline in four years, even as the city’s charter sector kept expanding — a divergence that is reshaping where the city’s children go to school and how the money follows them.

The Education Department’s preliminary figures put enrollment in the city’s K-12 and preschool programs at roughly 884,400 as of Oct. 31, 2025, down about 2.4% from the prior year. It was the biggest single-year drop since the early post-pandemic exodus.

The end of the migrant cushion

Officials did not immediately offer a single explanation, but the likeliest driver is the end of a years-long migrant influx. Over the three school years before this one, the city absorbed roughly 50,000 migrant students, a surge that helped offset an underlying decline and kept overall enrollment relatively flat between 2022 and 2024.

That cushion has deflated. With immigration into the country and the city sharply curtailed under the Trump administration’s enforcement push, the schools that had grown on the back of newly arrived students are now seeing their numbers fall — and the systemwide total is sliding with them.

No midyear clawback

Because school budgets in New York City are largely tied to enrollment, a drop of this size would ordinarily trigger midyear funding reductions for schools that came in under projection. In November, the Education Department announced it would not do that, holding schools “harmless” and declining to claw back roughly $250 million midyear.

The decision spared individual schools an abrupt budget hit but left open a structural question that carried into the new administration: whether the city can keep insulating school budgets from enrollment declines indefinitely. By February 2026, the durability of that hold-harmless approach under Mayor Zohran Mamdani had become an open policy debate, with the falling student count pressing on budgets that no longer match the formula.

Charters move the other way

While district schools contract, charter schools are growing. NYC charter enrollment rose about 2.3% from 2024-25 to 2025-26 and now exceeds 150,000 students — more than 16% of all K-12 public-school students in the city, and up roughly 18% since 2019-20.

The charter sector’s demographics underscore its footprint: nearly 31% of Black students in NYC schools attend a charter, and close to 90% of charter students are Black or Hispanic. As district enrollment falls, charters’ rising share intensifies long-running fights over space, co-locations, and the state cap on the number of charters allowed in the city.

The squeeze ahead

The combination — fewer district students, a swelling charter sector, and budgets still pegged to enrollment — sets up hard choices. Hold-harmless funding protects schools in the short run but widens the gap between dollars and students, a gap the city ultimately has to reconcile through some mix of closures, mergers, or budget restructuring. Chancellor Kamar Samuels has signaled openness to mergers and consolidations, and a shrinking enrollment base makes those conversations more likely, not less.

For now, the headline number stands: about 884,400 students in the district system, 22,000 fewer than a year ago, with the trend lines for charters and districts pointing in opposite directions.

No. The Education Department announced that schools with fewer students than projected would not have to return roughly $250 million in funding midyear under a 'hold harmless' approach.
What's happening with charter schools?
Charter enrollment grew about 2.3% year over year and now exceeds 150,000 students — over 16% of all K-12 public-school students in NYC, up roughly 18% since 2019-20.
