To what extent do women's organizations share a common commitment to organizational participatory democracy? Research suggests that women appear more likely than men to prefer democratic decision-making processes, yet these studies generally compare women's and men's behavior in organizations that are not only numerically dominated by men but that were also initially formed by men. I examine the electoral and policymaking rules of 37 membership-based women's associations in order to determine the extent to which the bylaws of women's groups exhibit the high levels of democracy predicted by the theoretical and empirical literature. I find that levels of democracy in women's associations vary more than research on women's governance would suggest. I then explore factors that influence the observed variation in women's groups. I find that the extent to which a women's group relies on membership dues, the year it was founded, and, to a lesser extent, its size affect how democratically it is structured. I conclude by considering the implications of these findings for the representation of women's diverse political and economic interests.
