Fertility response to natural disasters

"The event of a natural disaster, and being directly affected by it, brings a large shock to life-cycle outcomes. In addition to the replacement effects of higher fertility following a disaster that caused high mortality, a positive fertility response may be induced as children can be used to supplement household income. This paper analyzes three high mortality earthquakes: Gujarat, India, in 2001; North-West Frontier, Pakistan, in 2005; and Izmit, Turkey, in 1999. There is evidence of a positive fertility response to exposure to these large-scale natural disasters in addition to the response to child mortality. The results in this study are consistent with those of other studies that also find a positive fertility response following exposure to a disaster. "--World Bank web site.
