Abstract

This paper analyse changes in rates and differentials in fertility and contraception of the Northeast women. It also study the relationship between these two variables stressing female sterilization. The total fertility rate of these women has declined dramatically among all social groups and regions. This was provoked by female sterilization which was responsible for 70% of the Northeast prevalence in 1996. Regional and socio-economic differences almost disappeared so other methods became to be responsible for differences in fertility rates.
