Much evidence exists to show that white enrollment declines with the advent of desegregation. This study conducted in Jefferson County, Kentucky (Louisville) explains the causes of this decline in terms of birth rate decline, nonpublic school enrollment, and movement out of the county. A determination of the degree that each of these take place and their relationship to desegregation is made. In addition, interviews were conducted with affected parents to ascertain their attitudes toward desegregation related subjects, and to collect information on their demographic characteristics.
