In 2010, we saw the lowest reported birth rate in America in its history, since statistics were kept, going back to 1920.
This includes all ethnic and racial groups, and even immigrants, notorious for having large families, are having smaller families.
This is due to many factors, including birth control methods, greater education of women, need of wives and husbands to work to survive and prosper, and recognition that quality of life is enhanced by having fewer children.
This means over time that the population of the United States will continue to age, and that creates a problem of how to take care of older people as there are fewer young people who work and pay taxes, so Social Security, Medicare, and other programs will be affected long term.
This puts America into the category of European countries which are over time on a trend to lose population as they age, and the reality that the mass of younger population will continue to grow in the “third world” nations, particularly in Asia, which already has 60 percent of the world’s population as it is right now.
So western civilization, as we define it, may be in a long range decline as the fulcrum of world affairs, being replaced by China, India, Pakistan, Indonesia and other rising Asian powers that are constantly rising in population.
