INTRODUCTION
In this report we describe the fertility of an Amazon Indian tribe with one of the highest documented fertilities of any human group, a gross reproduction of 4.933 in 1964-69. This tribe, the Shipibo, is experiencing rapid cultural change which includes a decline in the prevalence of polygyny. We shall test the specific hypothesis that polygyny limits the fertility, both of individual women and of the community, through post partum sexual abstinence and longer birth intervals. The birth intervals of polygynously married women are longer, and their fertility is lower. The community's fertility rate is negatively associated with the proportion of polygynous birth intervals.
