I live in the U.S. and my parents had 9 children. My wife's family had 5 children. We hope to have 7. We do it for religious reason and that will not show up in anyone's stats. You never know what new religious beliefs people will adopt in the new millenium. They may want more children, they may want less. Wealthier countries tend to have less religious devotion than third world nations. Maybe that is why we are having less in the U.S. and more in Africa. If you want to keep the population down, keep people from praying and going to Church/Temple/etc.
