Based on the information provided by the National Socioeconomic Characterization Survey for 1990 and 2013, carried out by the Ministry of Social Development, the demographic changes of the sources and breadwinners in the household as well as the impact that a set of variables on women's economic contribution to the household would have are analyzed by means of Binomial Logistic Regression Models. The importance of the economic contribution of women to the household is observed, especially when it is obtained in remunerated work in socioeconomically disadvantaged groups and at female-headed households. Meanwhile, the State subsidiarity stops having woman as the only reference.
