Ethnic segregation as measured by the Entropy Index provides a measure of how homogeneous or diversified an area is in respect to others. Where the Index is computed as 0 this implies a fully homogeneous ethic composition. This dataset provides all 2011 Output Areas with a computed Entropy Index of 0. The dataset is based on univariate statistics on ethnicity at Output Area level as derived by Geolytix [geolytix.co.uk] and provided via the UK Data Service Census Support (UKBORDERS). The Entropy Index was derived using Apparicio, Philippe, Éric Fournier and Denis Apparicio (2012). Geo-Segregation Analyzer: a multi-platform application (version 1.0).
