For several good reasons the Index of Dissimilarity (D) has become the preeminent summary statistic for the measurement of spatial segregation. However, Lieberson's isolation index (P*) captures a dimension of segregation which is lost when only using D. When both measures are employed a much more complete description and analysis of trends is possible. This confirms the Duncans' (1955) conclusion that spatial segregation is too complex to be measured by one single summary statistic in isolation.
