note:As long as extended families provide working women (not only agricultural workers, but ones in urban areas having paid employment as well) with relatives who are willing to come and assist with household tasks and child care, paid female employment may not only make a far smaller contribution to fertility decline in tropical Africa than that observed in other regions, but it may also actually delay fertility reduction in Africa by slowing the trend toward the nuclear family system.Korotayev et al.
western highlanders (Semi-Bantu or grassfielders), including the Bamileke, Bamum (or Bamoun), and many smaller Tikar groups in the Northwest (est. In 2019 the natural increase was positive, as the number of births … Cameroon has a young population with a median age of 18.7 years and 41.25% of the population being between zero to 14 years old.

The latter risks were brought home with the outbreak of Ebola in the United States in 2014. This problem is likely to grow worse as Africa’s youth population grows in the context of inequality and corrupt autocratic regimes.Africa is also potentially a source of international risks in regard to climate change and disease. That was only twice the population of Japan, and only about one-third the population of Europe. As we have seen, secondary school enrollments in sub-Saharan Africa are poor. According to Bongaarts and Casterline, “… the median pace of change in sub-Saharan Africa (0.03 per year) is less than one-third the pace in the other regions [Asia and Latin America] (0.12 and 0.13, respectively).”Forecasting of Africa’s demographic trajectory based on expectations that it would follow the pattern of other regions has thus been badly misleading. For Africa as a whole, life expectancy in the 1950s was less than 40 years, not much different from Europe in the 1700s. This will create risks and anxieties, tempting the developed world to try to wall itself off from Africa. The data is given as of 1st of January of an year.

In Niger in 1998, for example, women who completed secondary education had 31% fewer children (on average, 4.6 per lifetime) than those who completed only primary education (6.7). The variation in the continent is too great.Africa today includes giant countries with populations near or exceeding 100 million (Egypt, Ethiopia, Nigeria) and tiny countries with populations under 1 million (Comoros, Djibouti, Cabo Verde, Reunion, Mayotte, Sao Tome and Principe, Seychelles). A sorghum and cassava “revolution,” along the lines of the “green revolution” that transformed Asia, is potentially within reach.The great difficulty is whether there will be jobs for those who move to the cities. This “medium variant” projection still presumes that fertility in sub-Saharan Africa will fall from an average of 5.1 today to 3.0 in 2050–55 and 2.2 in 2095–2100.

But because of the growing demographic weight of sub-Saharan Africa, the growth rate for Africa as a whole remained at 2.6 % per year up through 2015 and is projected (again, the medium variant projection) to decline only slowly to 2.5% per year by 2020 and 2.4% by 2025 as fertility falls. It shows the number of years a newborn infant would live assuming that birth and death rates will remain at the same level during the whole lifetime.According to our estimates 11,648,555 persons or 75.02% of adult population (aged 15 years and above) in Cameroon (See Figure 2)If we run the same path analysis on African countries, we would perhaps expect, following Bongaarts, that these relationships would still obtain but be weaker, or that, following Goujon, Lutz and Samir, that education would have a larger impact.

Also unusual is that in sub-Saharan Africa, unlike other developing regions, gains in income and urbanization have no direct effect on birth intervals at all; rather they act only indirectly through increasing women’s education.How is this possible?
Population Pyramids: Cameroon - 2055. In some sub-Saharan African societies, lifetime fertility is reduced only among girls who have had 10 or more years of schooling.However, despite its importance, the data on secondary school enrollments in tropical Africa tells a disappointing story.
