In order to describe the development and status of couples of any region, the historic, psychological and socio-cultural ecosystem in which they unfold must be specified. For this paper, the roots of Mesoamerican-Hispanic couples are described with emphasis on the norms and values that underlie the beliefs and behavioral patterns of contemporary males and females of this vast region. In a second section, the effects of modernization and female and child empowerment on traditional roles and couple relationships is covered. A third section is devoted to the analysis of the impact on family function and structure due to migration and acculturation of Mexicans and Central Americans who move north. As a corollary, an extensive description of research on the variables conducive to relationship maintenance with Mexican males and females is presented.
