<br/><br/> "According to the U.S. Census Bureau, 83 countries and territories, encompassing about 44 percent of the world's population, are now appearing below-replacement fertility. Nine of the 15 largest developing countries have fertility levels lower than that of the United States in 1965. The key number that demographers watch is the total fertility rate. A couple must have two children to replace themselves." (AMERICAN SPECTATOR) The author speculates that there will be a turning point in history when fertility rates will fall below replacement rates creating an underpopulation crisis.
