With data from census of the United States of America (US) and Spain, this article compares the occupational and household structures of the Dominican and Ecuadorian population in both countries. The main purpose of this work is to investigate (I) if the differences in the degree of feminization of the migratory flows towards both countries are related to the job market demand and (II) if this has had implications in the household structures of these migrants. The results suggest that the job market characteristics of the country of destiny might be behind the gender composition of the migratory flows to Spain and the US. In relation with the households, the female presence in complex households without a core is bigger in the collectives with more female presence. These differences are maintained when control variables are introduced, such as age, years of residence and the educational level of the migrants.
