The statement that is TRUE is: The NIR exceeds 2.0 percent in most countries of sub-Saharan Africa.
Here's a brief explanation for the other statements:
-
More than 95 percent of the natural increase is clustered in more-developed countries. This is false; the majority of natural increase occurs in less-developed countries, particularly in sub-Saharan Africa.
-
Regional differences in NIRs means that most of the world's additional people live in countries that are best able to maintain them. This is misleading. Countries with high natural increase rates often struggle with resources and infrastructure, which may not be able to sustain the rapid population growth.
-
The population of Europe is increasing because of high NIRs. This is not true; many European countries have low or negative natural increase rates and rely more on immigration for population growth.
-
Europe (including Russia) has had an increasing population since 1980. This statement is also false; many parts of Europe have experienced population stagnation or decline since 1980.
