[2] Pоpulаtiоn trends vаry tremendоusly from one region to аnother. Population growth increases as a result of increases in three rates: fertility, life expectancy, and immigration. Between now and 2050, the greatest growth is expected in the developing world, particularly in Eastern and Western Africa, where fertility rates remain high. For example, it is predicted that Nigeria will go from 160 million to over 400 million. In Ethiopia, an increase from 91 million to about 278 million is predicted. [3] In contrast, the population in Western Europe and especially Eastern Europe will either grow very slowly or in some cases decline. Compare the examples of Spain and Tanzania. The size of their populations is similar; both have a current population between 46 and 48 million. In 2050, Spain's population will be about the same as it was in 2010 whereas Tanzania's population is expected to triple. [4] Although Spain's population is predicted to remain about the same, some countries in Europe are experiencing a population decrease. This occurs as a result of several factors: a fall in fertility or life expectancy, or significant migration out of the country. In most Eastern European countries, fertilty rates have fallen below the replacement rate. In addition, life expectancy is lower in Eastern Europe than in many other parts of the developed world. This is especially true in Russia. Finally, in several Eastern European countries, many people have left for Western Europe of North America. What factor is NOT among the significant factors in population growth?
