Since 1969-70 the National Catholic Educational Association has published a statistical report on Catholic elementary schools and secondary schools in the United States. This year's report contains the core school enrollment and staffing data of the Association's historical file, and includes data from a survey on extended care programs and Chapter 1 services. The first part of the report presents a summary of the demographic trends that affect public and private education. Comparisons are made with other private schools and with the public sector. Population trends show increasing numbers of students at preschool and elementary school age levels. Catholic preschool enrollment tripled between 1982 and 1992, while elementary school enrollment has increased in 35 states. In 1991-92, there were 8,508 Catholic schools, of which 1,269 were secondary schools. The total number of Catholic school children was 2,550,863. About 23 percent of the students were members of minority groups. In 1991-92, non-Catholic students represented 12 percent of Catholic school enrollment. The student-teacher ratio for Catholic prekindergarten through grade-12 schools was 16.6. Extended care was offered by 3,087 elementary schools. Students in 4,323 Catholic elementary schools and 191 Catholic secondary schools received Chapter 1 services. There are 21 exhibits illustrating the discussion, and 3 appendixes provide additional summary reports. (SLD)
