I was fascinated to read that nearly half of the countries in the world had a declining population in terms of the number of children women are having. The surprising statistic would eventually have profound consequences in the future with there being a larger elderly population than there are younger generation.

In the UK birth rate per woman is 1.7, compared to Niger, West Africa at a whopping 7.1

The study suggests that more economically developed countries have lower fertility rates, they think this may be due to fewer deaths in children, improved access to contraception and more women in education and work.

The report goes on to suggest that migration is needed to increase the populations and potential ageing disparities. There is even a suggestion of rethinking the working age, suggesting that the current 67 will become unsustainable.
