Fertility treatment

摘要

Throughout most of the developing world, falling fertility has been a quiet, almost stealthy force improving people's lives. Because it is easier to educate two children than five, lower fertility goes hand in hand with higher skills and increased earning power in the next generation. With fewer dependent children, countries experience several generations in which working-age adults make up a disproportionate share of the population. That makes possible a "demographic dividend" of higher growth and rising incomes.
