Detailed explanation-1: -It suggests that as parents get richer, they invest more in the “quality” (for example, education) of their children. This investment is costly, so parents choose to have fewer children as incomes rise. Historically fertility and GDP per capita are strongly negatively related, both across countries and over time.
Detailed explanation-2: -In developing countries children are needed as a labour force and to provide care for their parents in old age. In these countries, fertility rates are higher due to the lack of access to contraceptives and generally lower levels of female education.
Detailed explanation-3: -South Korea has smashed its own record for the world’s lowest fertility rate again, according to official data. The average number of expected babies per South Korean woman over her reproductive life fell to 0.78 in 2022, down from 0.81 a year earlier, according to data published by Statistics Korea on Wednesday.
