|Figure 1-1: Percentage of the population ages 3-34 enrolled in school, by age group: October 1970-2010|
1 Beginning in 1994, new procedures were used to collect enrollment data on children ages 3–4. As a result, pre-1994 data may not be comparable to data from 1994 or later.
NOTE: Include enrollment in any type of graded public or parochial or other private schools and include nursery schools or preschools, kindergartens, elementary schools, secondary schools, colleges, universities, and professional schools. Excludes enrollments in schools that do not advance students toward a regular school degree (e.g., trade schools, business colleges, and correspondence courses). The enrollment rate for ages 18-19 includes enrollment at both the secondary level and the college level.
