developed world pop growth: mostly immigrants

The Financial Times on April 4 reported on a United Nations prediction that population growth in the developed world in the future may be almost entirely from international migration.
“Given the low fertility levels in developed countries, net migration has become the major source of population growth, accounting for half that growth in 1990-95, two-thirds in 1995-2000 and three-quarters in 2000-05,” the UN said. “If current trends continue, between 2010 and 2030, net migration will likely account for virtually all growth….“In addition, the governments of countries of origin have become more proactive in encouraging the return of their citizens and strengthening ties with their expatriate communities.”
The report, prepared for this week’s meeting of the Commission on Population and Development, said there were 191m migrants globally, up from 175m in 2000 and 155m in 1990. That represented a slowdown in growth compared with the 15-year period between 1975 and 1990, which saw 41m new migrants. But between 1990 and 2005, 33m out of 36m migrants moved to the developed world, with the US alone gaining 15m and Germany and Spain each accounting for 4m. The UN report said, “Today, one in every three migrants lives in Europe and about one in every four lives in northern America
