Statistical information on Catholic schools, enrollments, and faculty in the United States is presented in this collection of 18 tables. Comparisons are made where similar information is available on public schools and other private schools. Brief interpretive analyses focus on the significance of each table. In addition to enrollment figures and projections for Catholic, public, and non-Catholic private schools, the data presented shows the geographic distribution of Catholic schools and students, the distribution of students by ethnic background, and the distribution of religious and lay teachers among the teaching staffs of Catholic schools at the elementary and secondary levels.
