To quote the Commission on Population Growth and the American Future: The baby bust psychology may give rise to an unwarranted complacency born of the notion that all of the problems associated with population growth are somehow behird us. Our population growth has developed i s own momentum which makes it very difficut to stop. no matter how bard the brakes ..applied. Even if Immigration from abro.d ceased and couples had only two children on the averagejust enough to replace then:iselves--our population would continue o grow for about 70 years. The reason for this demographic fr et of life is the large number of young pcople just moving into their childbearing years. Even if they have small families on the average. the population will continue to expand throughout their lifetimes.
