An interesting article from The Economist. This needull discusses the growing issue of unfulfilled desire for children for a lot of couples.
Medical infertility is part of the problem, not just in rich countries, where couples put off having children until it is rather late, but also in poor countries, where health care is worse. By one global estimate, at least 48m couples have been trying for a child for the past five years but have not succeeded, up from 42m in 1990. But the main reason for the shortfall, according to our poll, is money. From Brooklyn to Beijing, the cost of housing and education is so high that many young people say they cannot afford as many children as they want.
