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. 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. The population pyramid that represents Stage 3 in the demographic transition has nearly vertical sides, with a broad base and relatively broad peak, reflecting reduced fertility, reduced childhood mortality, and increased survival; the older age categories make up a larger proportion of the population than in earlier stages, and the size of the population stabilizes. 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. "It's an African phenomenon of a large growing population and a large percentage of young people in the population.".
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. These are just a few of the linkages between population and land use/land cover (Lambin and others, 2001). 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. It suggests a growing population.
The life expectancy is also low – less than 50 in many nations and averaging 52 across the continent as a whole. but in Africa, the issue over family planning leads to the reverse effect.
Nigeria encompasses an extensive savanna region, without the extreme aridity found in the northern countries, and a large delta and coastal plains.
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. The UN Population Fund stated in 2009 that the population of Africa had hit the one billion mark and had therefore doubled in size over the course of 27 years. 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. Youth Dependency Ratio Definition: population ages 0-15 divided by the population ages 16-64.
Welcome to the United Nations. People tend to settle where the climate is clement, the soils are fertile, and economic opportunities are present. 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). The Population Fund’s Director Thoraya Obeid spoke to the BBC at the time and underlined the reasons behind the growing population. For comparison, the world population has increased less than three-fold during the same time period.
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. 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).
All three ratios are commonly multiplied by 100. A Population pyramid (also called "Age-Sex Pyramid") is a graphical representation of the age and sex of a population. 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. Many consider Africa's population growth a bit frightening, with predictions placing the continent's population at 2.4 billion by 2050. The boom in Africa's population will be in sub-Sahara, including growth in countries like Tanzania, which is one of the poorest countries on earth. Infant mortality is also extremely high, and in Mali, it is reported that there are 102 deaths per 1,000 live births. 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. Central Africa. 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.

Caribbees. With little or no measures in place to address the issue, the 2.4 billion prediction for 2050 is entirely plausible. 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. 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.
Africa currently has a very low population density of about 65 people per square mile, which puts it behind Asia, Europe, and South America.
In the arable regions, where soils are fertile and the climate is favorable for crop cultivation, higher population densities are found. The map of population densities (above) shows higher population densities in Nigeria than in any other West African country. Formula: ([Population ages 0-15] ÷ [Population ages 16-64]) × 100, Elderly dependency ratio Definition: population ages 65-plus divided by the population ages 16-64.Formula: ([Population ages 65-plus] ÷ [Population ages 16-64]) × 100, Total dependency ratio Definition: sum of the youth and old-age ratios. As an already very densely populated country today, Nigeria provides a preview of the pressures on the land resources that other parts of West Africa will likely have to face in the future.

The remaining 16 countries account for the other half of the West African population, with Ghana coming in at a distant second (7.5 percent of West Africa’s 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. Formula: (([Population ages 0-15] + [Population ages 65-plus]) ÷ [Population ages 16-64]) × 100.
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. schools, hospitals, homes, etc. All of these statistics could potentially lead to a fall in population numbers. South Africa. In most countries in the continent, the population growth is in excess of 2% every year.
In the densely forested southern part of the region, which has historically been more difficult to develop, rural population densities are generally lower than in the open savanna. 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. Most countries will at least triple in population as the region has very high fertility rates and very little family planning in most regions. Some portion of the population counted as "working age" may actually be unemployed or not in the labor force whereas some portion of the "dependent" population may be employed and not necessarily economically dependent.
