Abstract

A dramatic fall in fertility of Brazilian women has resulted in a rapid ageing of Brazilian population. The speed of this process has been much faster in Brazil than in most of European countries. This has marked social consequences. As a result of mortality differences, female population presents a larger proportion of aged persons than male population. For some time, Brazilian dependency ratio will decline which will allow a breath period before Brazil face an increase in this ratio. In this situation, the dependency ratio will change from an young dependency ratio to an old.
