This follow-up study of a 1979 survey of families involved in New York City's public day care program is based on field interviews with a random sample of 211 families in contact with the program in the past 4 years. Section 1 of this report describes the Agency for Child Development's day care programs for children from low-income working families and provides a description of the family survey, a rationale for and summary of results of the follow-up study, an overview of current funding patterns for day care, and recommendations. In section 2, lines of inquiry pursued in the follow-up study are described, including discussion of how families managed after being terminated from the day care program, what stresses they experienced, and how they rated the alternative arrangements they made. The several subsections of section 3 describe the following aspects of the follow-up study: (1) characteristics of the families involved; (2) choices made, criteria used, and barriers encountered by parents selecting child care; (3) difficulties in quantifying the number of children left alone while parents work; (4) alternatives used by families terminated from public day care or waiting to be enrolled, including a comparison between custodial and public day care; (5) satisfaction of parents with their day care arrangements; (6) case examples; and (7) the relationship between employment and child care.
