In many parts of the country, enrollment in traditional public schools has fallen to its lowest point in decades. However, states, cities, and school districts have been slow to respond to the reality of empty desks. This report examines trends in school enrollment, focusing on several of America's most populous cities, as well as the budgetary and staffing responses to those trends. It also examines the states where these large cities are located. Key findings include: (1) New York, Illinois, and California experienced the largest declines in enrollment between 2013 and 2022, while Texas and Arizona had the largest increase in enrollment; (2) Texas will soon surpass California with the most public school students; (3) In California's two biggest cities, Los Angeles and San Diego, enrollments fell between 2013 and 2022; (4) Philadelphia experienced a decline in enrollment that mirrored overall statewide trends; (5) Although Texas experienced a strong uptick in student enrollment statewide, its four biggest cities--Dallas, San Antonio, Houston, and Austin--all experienced slight declines over the last decade; (6) Costs per student rose between 2013 and 2022 in New York City, Houston, San Diego, Dallas, Austin, Philadelphia, Chicago, San Antonio, and Los Angeles; and (7) Total staff increased in New York, Chicago, Philadelphia, and Dallas over the 2013-22 period.
