In 2002, Seth Norton, a business economics professor at Wheaton College in Illinois, published a remarkably interesting study on the inverse relationship between prosperity and fertility. Norton compared fertility rates of over 100 countries with their index rankings for economic freedom and another index for the rule of law. “Fertility rate is highest for those countries that have little economic freedom and little respect for the rule of law,” wrote Norton. “The relationship is a powerful one. Fertility rates are more than twice as high in countries with low levels of economic freedom and the rule of law compared to countries with high levels of those measures.”
Economic freedom and the rule of law produce prosperity which dramatically lowers child mortality which, in turn, reduces the incentive to bear more children. In addition, along with increased prosperity comes more education for women, opening up more productive opportunities for them in the cash economy. This increases the opportunity costs for staying at home to rear children. Educating children to meet the productive challenges of growing economies also becomes more expensive and time consuming.
