This report is based on a survey undertaken by the Mayor's Office in Chicago to ascertain the effects of proposed HEW regulations for Title IV-A funds on the eligibility of families now using day care services in Chicago. The survey attempted to: (1) obtain actual profiles of the families currently using non-profit day care centers, (2) establish what the actual or potential costs of this care are to the public, and (3) make comparisons of these costs to welfare costs for those who would use Public Assistance as an alternative to day care. Based on 566 complete questionnaires, the following conclusions were made: (1) provision of quality day care services is enabling 45% of the respondents to stay off the welfare rolls and another 26% who are already receiving welfare to work or receive job training; (2) the services are making significant contributions to qualitative improvements in their clients' lives by making it possible for them to become self-supporting and for their children to have better opportunities for educational and social development; and (3) the clients are concerned parents, who care deeply about the quality of child care in the community. Parental statements and family profiles are included in this report. (DP)
