from The American:
Looking at the most recent United Nations’ population projections, it is likely that world population will peak somewhere between 8 and 9 billion near the middle of this century (current population is about 6.8 billion) and then begin declining back toward 6 billion by 2100.
In 2002, Seth Norton, a business economics professor at Wheaton College in Illinois, published a remarkably interesting study on the inverse relationship between economic freedom and fertility. Norton found that the fertility rate in countries that ranked low on economic freedom averaged 4.27 children per woman while countries with high economic freedom rankings had an average fertility rate of 1.82 children per woman.
