> > Over all no it's not as we have population declines everywhere outside the USA and Africa. The rate of increase is falling everywhere except sub-Saharan Africa, last time I checked a decade ago. Many developed countries have falling populations. It is still (as of a decade ago when I stopped actively studying this) a mystery as to why. It used to be thought that it was because of life long secure prospects for the children you do have and for yourself in old age. What children you do have will live, and you do not expect to need a lot of children to support you in your old age. But them some developed countries went into serious decline. The USSR, as was in particular. The population rate did not go up. The latest theory (a decade old, "latest") is that it has to do with the education of women. It has nothing to do with availability of contraception, surprisingly.
