CIA Factbook--growth rates by rank
Africa will be the source of the greatest increases in population growth. Notably, of all the continents, only Southern and Eastern Europe show negative growth rates in 2017, with Southern Europe at -0.12% and Eastern Europe at -0.15%. Europe as a whole has had a modest population increase of 0.08%, which is the smallest growth rate of the inhabited continents, although Western Europe continues to have a high population density of 178.31 per sq km. In contrast, all of the regions of Africa show significant population growth rates, with increases of 2.5-3% across Central, Eastern, Western and Sub-Saharan Africa.
