In Kentucky and around the nation, the cost of college attendance has risen steadily over the past two decades, while total undergraduate enrollment has leveled off or declined. Kentucky has taken aggressive measures to limit tuition increases and increase state and institutional aid; nevertheless, increasing college costs may be constricting our postsecondary enrollment pipeline, with negative consequences for Kentucky's educational attainment rates and economic well-being. This study investigates the relationship between affordability, unmet financial need, and retention to discern the precise values at which affordability concerns influence students' continued enrollment at Kentucky public institutions.
