You can use the Population Fact Sheet given in lecture to scan for regions or countries of the world that have the largest rates of natural increase; that is the largest per capita rates of increase. (You could focus on those that have rates near 3%.)
Doing this clarifies the truth of the statement that over 90 percent of the global increase in the human population is now concentrated in Asia, Africa and Latin America.
Several nations in 2008 had rates of natural increase near 3%, with a concentration in Africa and western Asia, and some fast growth nations also found in Oceania.
Fortunately, the nations with the highest rates of increase are mostly small nations (with small N), so they do not have much global impact
Yet the local impacts of such high growth rates are extreme! Nations with rates as high as 3.5% would double their populations in < 20 years if present per capita birth and death rates remained constant! It is difficult to imagine doubled populations for most of these nations, which are already facing extreme poverty and resource depletion...(Recall that you can estimate a population's doubling time by dividing 70 by its rate of natural increase as a percentage (r%).)
