A Comparison of Segregation Indices Used for Assessing the Socio-Economic Composition of Schools. Measuring Markets: The Case of the ERA 1988. Working Paper.
Gorard, Stephen; Taylor, Chris
This paper examines the changing socioeconomic composition of English and Welsh schools over 11 years following the Education Reform Act of 1988, using many indicators of socioeconomic disadvantage and methods of measuring the changing spread of disadvantage among schools (segregation). It explains how to assess segregation (percentage differences and indexes of segregation), then details the isolation index, the dissimilarity index, the Gini coefficient, and the segregation index, an alternative to the others. These indexes form a kind of hierarchical family. Using data on all English and Welsh schools over 11 years, results find high correlations for patterns of poverty among the various indexes. The segregation index and the dissimilarity index are the most highly correlated, while the isolation index has the strongest relationship with the population composition. The choice between the segregation index and the dissimilarity index and the others may make little practical difference in real-life situations, though differences are important and worthy of further investigation. The paper notes that the segregation index is the only index that can separate the overall relative growth of patterns of poverty from changes in the distribution of patterns of poverty among schools.
