Due to concerns about the impact of a shortage of child care on productivity, morale, attendance, and family life of members of the uniformed services, the General Accounting Office was asked to conduct a review to determine why and how the Department of Defense (DOD) provides child care, what child care services are available, how many children of what ages receive care, and how many children are waiting for care. The review covered military child care services provided by the DOD at Air Force, Army, Navy, and Marine Corps installations in the continental U.S. The report describes: (1) types of child care services provided in installations' child development centers and family day care homes; (2) the number and characteristics of children who were to receive child care in centers; and (3) the number of children who were on the centers' waiting lists. The report does not contain recommendations, but does present matters for congressional consideration. Appendices provide a military child care program questionnaire; a list of 219 CONUS (continental United States) installations which participated in the survey; supplemental data on military child care programs; comments from the DOD; and a list of major contributors to the report. Numerous tables and figures supplement the text. (RH)
