In this series: Iowa 2025-26 Enrollment.

A year ago, Iowa's enrollment losses looked manageable. The state dropped 3,820 students between 2023-24 and 2024-25, a modest acceleration from the 3,220 it lost the year before. A continuation of the slow bleed, but nothing that changed the conversation.

Then the Iowa Department of Education published its 2025-26 certified enrollment figures, and the number changed the conversation: 496,617 K-12 public school students, down 7,670 from the prior year. That is double last year's loss, the largest single-year decline outside of COVID, and it punches Iowa below 500,000 students for the first time in the data window. Whatever floor people thought they saw last year was not a floor.

What the numbers open up

The enrollment file covers 329 public school districts with breakdowns by grade level, race and ethnicity, and gender. Over the coming weeks, The IAEdTribune will unpack it in a series of data-driven articles. Here is what jumps out first.

Des Moines is no longer a white-plurality district. Hispanic students surpassed white students in 2025 and widened the gap in 2026. White enrollment in Iowa's largest district fell from 43.2% to 30.3% in 11 years, a pace of demographic change that has no precedent in the state. Meanwhile, the Des Moines metro's suburban ring grew by nearly 14,000 students over the same period. The students did not vanish. They redistributed.

Seven districts are now majority-Hispanic. The meatpacking towns of Postville, Denison, West Liberty, Storm Lake, Marshalltown, Perry, and Columbus Junction all crossed 50% Hispanic enrollment. Postville leads at 74.8%. Another eight districts are between 40% and 50% and closing fast.

By the numbers: 496,617 students statewide in 2025-26 — down 7,670 from the prior year, a 1.5% decline, Iowa's worst non-COVID year, and the first time below 500,000.

The threads we are following

72% of districts lost students. Of 329 districts, 236 shrank. Four have declined every single year for 11 consecutive years. The median district lost 11 students. The breadth of decline now matches the COVID crash of 2021, but this time there is no expectation of a bounce-back.

The kindergarten pipeline is collapsing. Iowa enrolled 34,748 kindergartners in 2025-26, the smallest K class in 12 years and a 13.0% decline from 2015. Total enrollment fell just 1.9% over the same period. Today's small kindergarten classes are tomorrow's small first-grade classes, and the year after that. Iowa's steepest losses have not happened yet.

Pacific Islander students nearly quadrupled. The fastest-growing demographic group in Iowa's schools is one most residents have never heard of: Marshallese families settling in meatpacking towns. Mason City went from 7 Pacific Islander students in 2015 to 228 in 2026. Ottumwa went from 29 to 475. The growth is 276% statewide, concentrated in six communities.

What comes next

Each of these threads will get its own article with charts, district-level breakdowns, and context from local reporting. New articles publish Tuesdays. The first deep dive, next week, looks at how Des Moines went from 43% white to 30% white in a single decade.
