After peaking at 6.3 million in the early 2000s, public school enrollment in California has marked its seventh consecutive decline in the 2023-24 school year, with projections indicating it could fall to approximately 5.2 million by the 2033-34 school year. This trend is attributed to lower birth rates, slowed immigration, and families relocating out of state due to high housing costs. Rural and coastal districts have been particularly affected, facing tough decisions such as school closures and staffing reductions.
Although chronic absenteeism in California decreased in 2023, it remains double the pre-pandemic rate. According to the Public Policy Institute of California, chronic absenteeism in the state public schools reached 25% in 2023, up from 12% in 2019.
