While civilizations flourished across the region in the 15th through 19th centuries, the high concentration of kingdoms, empires and particularly city states — such as Kano, Katsina, Oyo, Ife, Benin, Nri, Igbo and others— is unique to the territory that became modern Nigeria. Many consider Africa's population growth a bit frightening, with predictions placing the continent's population at 2.4 billion by 2050. What might explain this noticeable difference between Nigeria and the rest of West Africa?
"It's an African phenomenon of a large growing population and a large percentage of young people in the population.". It suggests a growing population. The population pyramid of China (below) from 1950 to 2050(expected) shows the impact of One-Child-only policy that was introduced in 1979 due to the extreme rise in population. In the arable regions, where soils are fertile and the climate is favorable for crop cultivation, higher population densities are found.
This is a five-fold increase in population since 1950, when 73 million people lived in the region, which makes West Africa the fastest growing of any of the world’s regions. This is pretty amazing considering the country is about the size of Texas. NOTE: Dependency Ratio does not take into account labor force participation rates by age group. Dietary demands of the urban population translate into land demands in the urban periphery, in particular for the cultivation of high-value, perishable crops, such as fruits and vegetables. World Population Prospects 2019 41% of the African population is under the age of 15. boom in Africa's population will be in sub-Sahara, World Population Prospects (2019 Revision), Democratic Republic of the Congo: 71,246,355, Saint Helena, Ascension and Tristan da Cunha (UK) (non-sovereign): 4,124. Welcome to the United Nations. The map of population densities (above) shows higher population densities in Nigeria than in any other West African country. View live population, charts & trends: Population of South Africa, A Total Fertility Rate (TFR) of 2.1 represents the Replacement-Level Fertility: the average number of children per woman needed for each generation to exactly replace itself without needing international immigration. Any expert would find it hard to argue with the commonly held view that the population of Africa in 2016 and beyond is set for further increases. Just 13 years ago, the country's population was 34 million, which has now grown to 45 million but is projected to reach 276 million by 2100, which is close to the current population of the U.S. A population pyramid, also called an "age-gender-pyramid", is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which forms the shape of a pyramid when the population is growing. As much of Africa is still developing, and it contains some of the poorest countries on earth, time will tell how it will sustain such massive population growth. West Africa’s population is unevenly distributed throughout the region, reflecting differences in the physical environment as well as the history of human settlement (see map above). The young age structure of the West African population — almost half of West Africans are 15 years old and younger — assures continued population growth into the near and medium future. People tend to settle where the climate is clement, the soils are fertile, and economic opportunities are present. Settlements are also concentrated in the riverine plains of the Senegal and Niger rivers, where perennial water availability supports irrigated agriculture of rice and high value garden crops. Caribbees. miles). However, along the coast, population densities are driven up by a large number of coastal settlements, including some major urban agglomerations. The population of Africa is currently projected to quadruple in just 90 years, with a growth rate that will make Africa more important than ever to the global economy. By comparison, the age structure of the global population has moved toward a more rectangular shape, describing a population that is only slowly expanding, with lower birth and death rates and more people living to old age.
A value below 2.1 will cause the native population to decline, See also: Countries in the world ranked by Life Expectancy. 54 countries make up the continent of Africa, and while population growth is relatively low in some areas, countries such as Nigeria and Uganda are increasing at an advanced rate. This has reduced considerably over the course of the last twenty years with a widespread HIV and AIDS epidemic taking much of the blame for that statistic. These are just a few of the linkages between population and land use/land cover (Lambin and others, 2001). In former British colonies, this can be seen extensively, and Kenya, Tanzania, Uganda, and South Africa are all good examples as to a growing set of diverse ethnicities. but in Africa, the issue over family planning leads to the reverse effect. The African nations as a whole are made up from such a diverse set of components that it is impossible to list them in full concerning demographics. A majority of West Africans still live in rural areas, yet the urban population has increased from only 8.3 percent in 1950 to almost 44 percent in 2015. All of these statistics could potentially lead to a fall in population numbers. For comparison, the world population has increased less than three-fold during the same time period. "African countries are all growing fast ... because there is a large number of women who have no access to planning their families," she said. A population pyramid, or age structure graph, is a simple graph that conveys the complex social narrative of a population through its shape. Population pyramids for selected countries in the regions of the world This page is a companion page to: UN Population Policies, World Demographics, Job Fatalities and The Extermination of Men. With little or no measures in place to address the issue, the 2.4 billion prediction for 2050 is entirely plausible. Part of the wages earned in the city reach the rural areas in the form of remittances to the homelands of the new urbanites, where they spur investments in economic activities that potentially affect the land cover, such as through abandonment or intensification of agriculture. Department of Economic and Social Affairs Population Dynamics. Expansive - pyramid with a wide base (larger percentage of people in younger age groups, indicating high birth rates and high fertility rates) and narrow top (high death rate and lower life expectancies). The age structure of West Africa’s current population forms the shape of a pyramid with a wide base and concave sides, indicating a high birth rate and a relatively high death rate, resulting in rapid growth. Central Africa. Nigeria is set for one of the biggest population booms in world history and it's expected to increase by a factor of eight in just two or three generations. The age structure of West Africa’s current population forms the shape of a pyramid with a wide base and concave sides, indicating a high birth rate and a relatively high death rate, resulting in rapid growth.

However, in certain parts of the continent, there has been an increase in Asian and European settlers, which has also served to boost the population statistics as a whole. Thus, the Peanut Basin of western Senegal, the Niger-Nigeria border region, central Burkina Faso, and southwestern Chad stand out by their relatively high rural population densities.
Assuming a medium fertility model, the population of the region is projected to exceed one billion by 2059, when almost one in 10 of the world’s people will be West African (UN, 2015). In addition, there is a high proportion of younger people within the Africa population as a whole, with reports that 41% of the African population is under the age of 15. The changes in lifestyle and consumption patterns associated with a progressive urbanization of the population affect land use and land cover patterns beyond the obvious increase of built-up area (Rindfuss and others, 2004). Formula: (([Population ages 0-15] + [Population ages 65-plus]) ÷ [Population ages 16-64]) × 100. In the arid northern part of the region, only a small, sparse population can be sustained. Two out of the three ancient trans-Saharan trade routes originating from North Africa and Arabia ended in Nigeria, which brought an influx of people to settle and trade. Africa's Nigeria is currently one of the most populous countries on earth, and as China's population shrinks and India plateaus, Nigeria will reach nearly 1 billion people by 2100 and come close to surpassing China.
