Recent research suggests that rural people develop a rich array of informal support and exchange among their kin, neighbors and friends. These informal exchanges are argued to develop in response to the weak penetration of formal state structures and capitalist market relations in peripheral regions. This case study of the survival strategies of low income rural mothers who live in Quebec village demonstrates that these mothers avenues for economic and social integration are restricted by the formal and informal sectors which constitute and reinforce one another. First, an extensive data and document analysis of the Quebec pronatalist and welfare policies reveals that they fail to provide low income rural women access to appropriate training and education, to transportation and adequately subsidized child care, or to secure jobs. This restricts these womens integration into formal or informal systems of support and exchange. The second section draws on interviews with 20 community leaders and on two years of participant observation. Contrary to the literature which suggests that extensive informal ties promote socially and economically inclusive rural communities, this case study reveals that centralized state development policies limit local community initiative and independence. Hence, community effort to aid low income families are limited to charity which does not fundamentally alter these families marginal position. The third section draws on semi-structured interviews with 20 low income single and married (or common-law) mothers. Comparing the single and married mothers strategies reveals that studies of the rural informal sector have narrowly defined the sector, by excluding unpaid domestic and child care work. It is shown that the married mothers strategy to stay in the home is a viable one because she alone performs the unpaid work of the home. This results in her isolation in the domestic sphere. For the single mothers who seek paid work, the gendered nature of the informal sector coupled with the poor formal employment opportunities only reinforce their confined position. This analysis demonstrates the necessity of more broadly defining the informal sector and of linking it with the formal structures which together marginalize rural low income mothers.
