California schools confront shrinking enrollment as birth rates and out-migration fall

Research from the Public Policy Institute of California shows an 8% reduction in K-12 enrollment across the state since 2015, shrinking the student body from about 6.2 million to just under 5.7 million. The decline is driven by falling fertility rates—down from 2.21 children per woman in 2007 to 1.48 in 2023—combined with high housing costs and changing lifestyle choices among people in their twenties. Additionally, California has experienced the largest net domestic outflow in the country, with almost 10 million residents moving to other states since 2010.

Educators describe the impact as frequent grade reassignments and worries that political concerns are pushing families toward homeschooling or out-of-state moves. Lafortune cautions that the demographic cascade will likely continue, potentially affecting school district planning, the future workforce, and even congressional representation. He emphasizes that the trend appears slow-moving and not poised for a quick reversal.
