Reducing poverty and social exclusion is an important objective for all French governments. Even though conventionally measured poverty is in fact lower than in most other countries, it is still higher than can be easily accepted. The current policy approach involves a large number of measures tailored to different circumstances. Some policies have unwanted side effects on labour market performance, and their cost-effectiveness could be improved to obtain better outcomes with the same resources. Concentrations of poverty and social exclusion in certain geographic areas and among certain groups of the population provide one of the most difficult challenges, for which contributions from education, labour market, housing, urban planning and anti-discrimination policies, as well as from the social services, are necessary. This Working Paper relates to the 2007 OECD Economic Survey of France (www.oecd.org/eco/survey/france), and is also available in French under the title "Lutter contre la pauvreté et l'exclusion sociale en France".
