|Figure 2-1: Percentage of 3-, 4-, and 5-year-old children enrolled in full-day preprimary programs: Selected years, 1980 through 2010|
NOTE: Data from 1995 to 2010 were collected using new procedures and may not be comparable with data prior to 1995. Preprimary programs are groups or classes that are organized to provide educational experiences for children and include kindergarten, preschool, and nursery school programs. Enrollment data for 5-year-olds include only those students in preprimary programs and do not include those enrolled in primary programs. Data are based on sample surveys of the civilian noninstitutional population. For more information on the Current Population Survey (CPS), see Appendix B – Guide to Sources.
