This document presents the preliminary analysis and findings of the first three parts of the Family and Community Impact Study designed to investigate the influences of day care on families and communities in Pennsylvania. The three reports discuss: (1) parent participation in day care and the relationship between the use of day care facilities and marital satisfaction; (2) the relationship between day care facilities and the community, described in terms of community participation and the utilization of community services; and (3) the impact of day care on family economics, described in terms of family income, rate of employment of spouses, and use of free time by the unemployed day care mother. Data were obtained from parents who had a child in day care or were waiting to place a child. Data tables and bibliographies are included. (CS)
