Human survival probability and fertility decline strongly with age. These life history traits have been shaped by evolution. However, research has failed to uncover a consistent genetic determination of variation in survival and fertility. As an explanation, such genetic determinants have been selected in adverse environments, in which humans have lived during most of their history, but are alm...

As a result, fertility has reached very low levels in many countries. In addition, currently more than 40 per cent of the world’s population lives in countries with total fertility levels lower than 2.1 children per woman, the level tha...

In the early 1960’s Pakistan was the pioneer country which focused on the family planning issues to control the fertility rate so that population growth would be controlled. But it has been observed that the population growth could not be controlled at the desired level yet. The main objective of this study is to explore the factors ...

We hypothesize that the perceived returns to human capital and to income uncertainty are important determinants of recent cross-sectional variation in Latin American fertility. An empirical study of cross-country individual level data supports the hypothesis. In particular, we find that a higher perceived return to human capital and higher income uncertainty both lead to higher fertility, all e...
