The role of sterilization in controlling Puerto Rican fertility

This paper provides evidence that the prevalence of female sterilization in Puerto Rica has increased substantially in recent years. It is estimated that about one-third of all Puerto Rican mothers aged 20 to 49 in 1965 were sterilized. This estimate is based on data from an island-wide survey in 1965 (Master Sample Survey of Health and Welfare). Additional data from this and other sources are analysed, leading to the conclusion that sterilization, rather than any other means of fertility control, was largely responsible for the decline in Puerto Rican fertility since 1950.
