The suburbanisation of poverty has been noted in the cities of a large number of countries, including the UK. The main drivers are labour market restructuring on the one hand, and market-driven change in the housing system on the other although social and housing policies are also factors. This paper explores the possible consequences for the welfare of low-income groups in relation to two dimensions: exposure to air pollution and access to good quality schools. Results show that, for these groups, suburbanisation has had mixed impacts on welfare. In most cities, suburbanisation is likely to bring improvements in air quality but there are only a minority where it improves access to good quality schools. Overall, it is clear that suburbanising low income households enjoy fewer of the benefits of suburban locations than middle class households.
