Descriptive analysis of state enrollment data shown in Figure 1. The report notes the proportion of eligible 4-year-olds enrolled declined "from 64% in 2021–22 to 59% in 2023–24" because the eligible population increased.

"Since TK expansion began, TK enrollment has increased substantially, growing from 88,883 children in 2019–20 to 151,491 in 2023–24"
