Abstract
The early childbearing constitute a serious social problem and affect the development of adoles-cents, their health and the survival of their sons and daughters. There is a strong linkage between poverty and pregnancy at an early age, as this is more frequent among poor young women. A detailed analysis of this phenomenon in Mauritania allows us to perceive notable geographical differences related with these reproductive patterns within the country. Therefore this paper aims to inquire into the geo-demographic and socio-demographic factors conditioning the early child-bearing in Mauritania, to provide some reflections regarding the environments that must be taken into account to develop intervention programs that reduce their incidence.
