Unlike grade schools, who welcome returning students, Pre-K populations are often new and unknown. Previously, school enrollment figures were only gathered at the time of enrollment—after planning and budgeting have already been completed for the current school year. While school administrators can hire consultants to develop forecasts of the overall student population, these forecasts are static and do not typically address new programs like Universal Pre-K. If they do, they are based on demographic data that is not up-to-date or nuanced enough to detect intersections of demographics such as income, race/ethnicity, and more.
