London has become an ethnically much more diverse city over recent decades but has that growing macro‐scale diversity been replicated in its myriad neighbourhoods? Using recently released 2011 census data and an established methodology for classifying small areas according to the ethnic composition of their populations, this paper explores the extent and nature of change in those areas over the decade 2001–2011. It identifies two main patterns: firstly, in many parts of London where Whites previously predominated neighbourhoods are more mixed ethnically; secondly, in those areas where Whites were in a minority by 2011 there were even fewer Whites but without the development of separate enclaves where one Non‐White group predominates. The result is an ethnic landscape characterised by two types of changing diversity. Copyright © 2013 John Wiley & Sons, Ltd.
