Lardoux Solène, van de Walle Etienne.- Polygyny and Fertility in Rural Senegal The aim of this study is to look at some determinants of fertility differences between monogamous and polygynous wives of ranks 1 to 3 or higher in two rural regions of Senegal. The measure of fertility is a dichotomous variable that refers to the occurrence of a birth during the 12 months prior to the census date. The analysis of cross-sectional data for the rural Tambacounda and Kolda regions from the 1988 Senegal census allowed us to test our hypotheses and to find the following results: first, the fertility of each wife decreases with the number of wives in the union; second, the wife of highest rank is more likely to have given birth in the previous year than her co-wives; as for the age of the husband, it appears to have a stronger effect for monogamists than for polygynists, for whom it is substantial only after 60; childbearing by one wife during the previous year increases the probability of a birth to a co-wife; finally, the presence of a first wife past the age of childbearing has no effect on the fertility of her co-wives.

Lardoux Solène, van de Walle Etienne.- Poligamia y fecundidad en el medio rural senegalés Este estudio tiene como objetivo examinar ciertos déterminantes de las diferencias de fecundidad entre las mujeres que viven en union monógama y las que viven en union poligama (esposas de rango 1 a 3+) en dos regiones rurales de Senegal. La variable analizada es una variable dicotómica que indica si ha tenido lugar o no un nacimiento durante los 12 meses an- teriores al censo. El análisis de datos transversales del censo senegalés de 1988 relativos a las regiones de Tambacounda y Kolda nos permiten verificar cinco hipótesis y obtener los resul- tados siguientes: en primer lugar, la fecundidad disminuye a medida que aumenta el numero de mujeres en una union. En segundo lugar, la esposa de rango más elevado tiene más proba- bilidades de haber dado a luz durante el afio de referencia que sus coesposas. En cuanto a la edad del marido, su efecto es más importante entre las monógamas que entre las poligamas; entre estas ultimas, el efecto sólo es significativo a partir de los 60 aňos. La presencia de un nacimiento durante el afio de referencia aumenta la probabilidad de que una coesposa también de a luz. Finalmente, la presencia en el seno de la union de una primera esposa que ha termi- nado la etapa fecunda no afecta la fecunidad de las coesposas.
