1. People are getting older
Thanks to medical progress and better living conditions, we live longer than ever before. This applies to both industrialized and developing countries. While the average number of children per woman is decreasing almost anywhere in the world, people in many parts of the world reach a world-wide unrivaled age.
2. More children survive
Thanks to the industrial revolution and worldwide progress in the health sector and the food situation, child mortality fell only in the industrialized countries and later also in the developing countries.
But: That more children survive is also a reason for many parents to get fewer children. High survival chances of children lead to a decline in the birth rate, because parents have to worry less about the survival of their own children.
