Résumé :	[BDSP. Notice produite par INIST-CNRS 97R0x8J8. Diffusion soumise à autorisation]. Background : Many epidemiological studies require a measure of socioeconomic position. The monetary measure preferred by economists is consumption expenditure ; the wealth index has been proposed as a reliable, simple alternative to expenditure and is extensively used. Methods : A systematic review was conducted of the agreement between wealth indices and consumption expenditure, summarising the agreement and exploring factors affecting agreement. Results : Seventeen studies using 36 datasets met the inclusion criteria. Of these, 22 demonstrated weak agreement, 10 moderate agreement, and four strong agreement. There was some evidence that agreement is higher : in middle-income settings ; in urban areas ; for wealth indices with a greater number of indicators ; and for wealth indices including a wider range of indicators. Conclusions : The wealth index is mostly a poor proxy for consumption expenditure.
