Abstract

The Pacific society in Central America was product of intense social and geogra phical mobility of the 18th century economic model. This mobility led to a set of practices that changed the family, especially in areas of considerable productive intensity such as San Salvador and Sonsonate . This work, which is part of a larger study, aims to expose some of the ways in which the phenomenon was expressed, from a socio-biological approach, unusual for the region. To do this, the article is mainly based on the study of works related to the American field and several documents from Central American archives.
