The at-risk-of-poverty rate is a key monitoring indicator in connection with the European Union’s goal to take 20 million people out of the risk of poverty and social exclusion by 2020. Whilst there is comprehensive and up to date coverage at the national level, much less is known about how different regions are performing in this respect. This paper illustrates how the World Bank poverty mapping methodology, combined with the European Union Statistics on Income and Living Conditions (EU-SILC) survey, can be used to compute small area estimates of at-risk-of-poverty rates for the UK, and compares the obtained estimates with existing estimates of relative poverty obtained using national surveys. There is considerable spatial dispersion in at-risk-of-poverty rates. The highest rates tend to be found in large cities, but there are also relatively high rates in some remote rural areas. Furthermore, regional differences in housing costs can act as an important driver of poverty, particularly in large cities. Our analysis suggests that the EU-SILC survey, combined with national population census data, can provide a practical basis for developing regional or local estimates of at-risk-of-poverty rates across EU Member States, which would be particularly valuable where national surveys have inadequate regional sampling.
