The purpose of this report is to assemble in a single volume the latest available data on current trends and projections of births and enrollments made by various agencies such as the National Center for Education Statistics, the National Center for Health Statistics, the U.S. Bureau of the Census, and others to assist school management in decisions relating to facilities planning, staffing, and finance. The study is intended primarily as a reference manual not only to familiarize school officials and other planners with important sources of information relating to enrollment and birth trends, but also to provide a ready source of the available statistical data needed in educational planning. Chapters include enrollment trends and projections (grades K-12, K-8, 9-12), school-age population trends and projections (ages 5-17, 5-9, 10-13, 14-17), population migration, and birth and fertility trends and projections (female population in the childbearing years, births and birth rates, birth control--contraception and abortion, and birth expectations and fertility rates). Data in 30 tables and three figures are discussed.
