Demographic and marketing data was collected to justify the development of a television series for preschool children. The terms "demographic" and "marketing" have been constricted in meaning for pertinence to educational program development. Demographic points were made pertaining to population, family income, percent of families below poverty level, women with own preschool children, families with preschool children and the population of 3-, 4-, 5-year-old children in Appalachia. The points were based principally on county data from the 1970 census conducted by the United States Bureau of the Census. Selected marketing data are presented pertaining to television households, television station distribution in Appalachia, and broadcast coverage of the region. The data are principally based on the "Television Fact." Appendices together with a numerous list of tables and figures are included. (WCM)
