A recent edition of this Journal (Volume 16, Part 2, April 1987) was devoted to a number of articles on the definition and measurement of poverty. Surprisingly, perhaps, this did not include any specific discussion of gender differences in the causes, extent and experience of poverty. But such gender differences do exist, though they are often obscured by much research on poverty. Our initial response to the special edition on poverty was to write a reply discussing how the various contributors had ignored the issue of gender. But women cannot simply be ‘added in’ to existing analyses; instead a different analytic framework is required. This article therefore begins by looking at some of the widespread evidence of the economic disadvantage of women compared with men. We then go on to discuss why it is necessary to focus on the gender dimensions of poverty. We argue that this involves far more than simply disaggregating data to produce statistics about the situation of women. Rather, this focus leads us to explore the structural causes of women's poverty and the gendered processes in the labour market, welfare systems and domestic household which interact to create and maintain that disadvantage. In the final section we consider some of the important conceptual and methodological issues which must be tackled if we are to find ways to investigate and measure poverty which are not gender-blind.
