Answer:
Describe the population growth trend in sub-Saharan Africa, and explain why this is occurring.
Explanation:
(1) The population of sub-Sahara Africa has grown from 186 million to 856 million people from 1950-2010. That’s about 11 million people a year for the past 60 years or approximately 670 million people in 60 years. By 2060, the population of sub-Sahara Africa could be as large as 2.7 billion people. Compare this demographic shift to Europe’s projection of a declining population—from 738 million people in 2010 to 702 million in 2060.
(2) Nigeria, Ethiopia, Tanzania, DRC, Niger, Zambia, and Uganda will contribute millions of people to the world total. Along with China and India, these countries will have the largest populations in the world. By 2050, Nigeria is projected to outpace the population of the United States by about 30 million people.
(3) These staggering numbers are the results of decades of change in childbearing and mortality patterns. Until recently, on average a woman in sub-Sahara Africa had 6.5 children over her lifetime. Now women have 5.1 children on average, but this average masks considerable heterogeneity; in countries like Botswana, South Africa and Kenya women have fewer children, but in countries like Niger or among less educated rural poor women, the change is minimal, if any.
(4)Deaths, especially those of children, are increasingly being reduced. Infant mortality rates have declined from 183/1000 children born in 1950-55 to 69/1000 children born in 2010-2015. As a result, life expectancy has increased from 36 years in 1950-55 to 56 years at present.
(5) Policies and public actions matter to population growth. The large variations in population across countries are caused by factors such as levels of education, poverty, urbanization, access to health care including family planning methods and attitudes towards population growth. These factors help to explain why, for example, Niger’s population is growing at 3% per annum while Botswana’s population is growing at 1% per annum. Women have fewer children when they marry later, start families later and use modern methods of family planning. Childhood deaths have been reduced in countries with better access to immunization, health care, nutrition, education and transport.
