Where to find country population, migration and related projections

Go here, A U.N. website, to find past figures from 1950 and projections through 2050. It shows that Japan and Italy will begin to experience population declines in 2010-2015 and France after 2035. Canada and Australia will have very strong immigration rates (over 5% of population in many years). The U.S. follows. The immigration rates of Western European countries are much less. Mexico will export people at a substantial rate.
