2.1 million fewer children: US school enrollment hits historic low

The population of children under age 18 in the United States dropped by roughly 2.1 million between 2010 and 2025.

This steep decline, tracked by U.S. Census data, marks the first time in nearly a century that both birth rates and immigration levels have remained low simultaneously. The shift has moved from a slow demographic trend to an urgent fiscal crisis for public education systems nationwide.

According to the U.S. Department of Education, public school enrollment peaked in 2019. By the 2024 school year, that number had fallen by approximately 1.5 million students. Federal researchers project the decline will accelerate, with at least another 2 million students leaving public classrooms by 2030.

That trajectory represents a 7% national drop in roughly a decade. The financial impact is severe. A June report from education think tanks Bellwether and WestEd estimates that falling enrollment will cost public schools $11 billion a year in funding.

The data shows this is not a localized issue. A joint analysis from Bellwether and WestEd found that enrollment is declining in 40 states. The primary driver remains the sustained drop in birth rates, compounded by a national slowdown in immigration.

In Los Angeles, the effects are visible on the ground. LA Unified School District, the second largest in the country, lost more than 300,000 students over the last two decades. Kelly Gonez, a board member, noted that the district predicted a 2% drop in enrollment this year. It ended up being double that.

Guadalupe Cardona, a teacher at Santee Education Complex in South Los Angeles, reported that over 200 students did not show up on the first day of the 2026 school year. Many families left without notice. The school lost two teachers in the early weeks of the term.

Other states report similar sharp losses. Texas saw a statewide drop of more than 76,000 students last year. Florida’s Miami-Dade and Broward County districts lost roughly 30,000 children combined in a single year, a decline linked to the removal of temporary protected status for Haitian refugees.

Thomas Dee, an economist at Stanford University, stated that to stop or slow immigration exacerbates the problems of demographic decline. He noted that communities are now confronting painful decisions about closing schools.

LAUSD announced a citywide effort in September to identify buildings and campuses that will close. Gonez said the district expects cuts to be deep. When a district is roughly half the size of its student population from 20 years ago, finding a sustainable path to keep campuses open is difficult.
