This report attempts to provide a standardized evaluative measure for both school desegregation initiated by administrative action and the result of that action or lack of action. The latter measure, the measurement of school integration, involves two techniques--a uniform standard index which sets the same goals for all school districts, and one which sets appropriate goals for each school district by taking into account politically feasible black-white ratios in individual schools. The 90 northern cities in our sample are ranked according to their scores on these three measures. In this report we will first describe how we collected our data, and from it computed a measure of desegregation action from 1964 to 1971. The second section presents the index of dissimilarity of segregation in each school district. The third section indexes the degree of desegregation possible in each district taking into account the need for politically racial compositions. Then in the fourth section we will look at the amount of administrative action which has taken place in each measured district compared with the above indexes of desegregation. Fifth we present a regression analysis in an effort to explain and predict the differences between cities in degree of segregation. Finally, we look at yearly trends in desegregation in these cities.
