The major purpose of this paper is to increase employers' awareness of the impact that the rising number of working mothers has had on the need for day care in Arkansas as a whole and in their specific business locales. It is hoped that employers will be motivated to investigate and evaluate the advantages of providing some form of day care assistance as a fringe benefit. The paper estimates the number of children under age 6 who require some form of day care because their mothers work. It also estimates the number of school children ages 6 through 12 who require supervision after school, during school holidays, and during summer vacations because their mothers work. To serve the needs of different readers, the estimates are both for the state and for each of the 75 counties. In addition, estimates of the number of preschoolers whose mothers are in the labor force are made for a 30-mile radius around 16 labor centers. Statewide estimates are presented by race, by number of parents with whom the children live, and by urban or rural residence as defined by the 1980 Census. Appendix A lists the advantages and disadvantages of various options available to employers to assist their employees. (RH)
