The concept of the informal sector as a descriptive and analytical category and as a focus for policy planning and program intervention has grown in importance since the International Labour Organization adopted it in the early 1970s. 1 Research on the informal sector developed into a salient theme in the literature on the labor-market and labor-process in both post-industrial societies and post-colonial states. But in much of this literature there is a striking absence of any discussion of women or the divisions of labor that shape informal sector work.
