Africa's population is projected to grow significantly in the coming years. Estimates conducted in July 2020 show that Nigeria, the most populous country on the continent, would reach around 790 million inhabitants by 2100. Compared to 2021, when the country counted 211 million people, this would represent an impressive growth of around 274 percent. The Democratic Republic of the Congo is estimated to be the second most populous nation on the African continent, reaching 246 million individuals. According to the study, nine countries in Africa would exceed 100 million people by 2100.

From now until 2100, India and China will remain the most populous countries in the world, however China's population decline has already started, and it is on course to fall by around 50 percent in the 2090s; while India's population decline is projected to begin in the 2060s. Of the 10 most populous countries in the world in 2100, five will be located in Asia, four in Africa, as well as the United States. Rapid growth in Africa Rapid population growth across Africa will see the continent's population grow from around 1.5 billion people in 2024 to 3.8 billion in 2100. Additionally, unlike China or India, population growth in many of these countries is not expected to go into decline, and instead is expected to continue well into the 2100s. Previous estimates had projected these countries' populations would be much higher by 2100 (the 2019 report estimated Nigeria's population would exceed 650 million), yet the increased threat of the climate crisis and persistent instability is delaying demographic development and extending population growth. The U.S. as an outlier Compared to the nine other largest populations in 2100, the United States stands out as it is more demographically advanced, politically stable, and economically stronger. However, while most other so-called "advanced countries" are projected to see their population decline drastically in the coming decades, the U.S. population is projected to continue growing into the 2100s. This will largely be driven by high rates of immigration into the U.S., which will drive growth despite fertility rates being around 1.6 births per woman (below the replacement level of 2.1 births per woman), and the slowing rate of life expectancy. Current projections estimate the U.S. will have a net migration rate over 1.2 million people per year for the remainder of the century.

Total current population for Nigeria in 2025 is 234,573,603, a 2.37% increase from 2024.

The world's population first reached one billion people in 1803, and reach eight billion in 2023, and will peak at almost 11 billion by the end of the century. Although it took thousands of years to reach one billion people, it did so at the beginning of a phenomenon known as the demographic transition; from this point onwards, population growth has skyrocketed, and since the 1960s the population has increased by one billion people every 12 to 15 years. The demographic transition sees a sharp drop in mortality due to factors such as vaccination, sanitation, and improved food supply; the population boom that follows is due to increased survival rates among children and higher life expectancy among the general population; and fertility then drops in response to this population growth. Regional differences The demographic transition is a global phenomenon, but it has taken place at different times across the world. The industrialized countries of Europe and North America were the first to go through this process, followed by some states in the Western Pacific. Latin America's population then began growing at the turn of the 20th century, but the most significant period of global population growth occurred as Asia progressed in the late-1900s. As of the early 21st century, almost two thirds of the world's population live in Asia, although this is set to change significantly in the coming decades. Future growth The growth of Africa's population, particularly in Sub-Saharan Africa, will have the largest impact on global demographics in this century. From 2000 to 2100, it is expected that Africa's population will have increased by a factor of almost five. It overtook Europe in size in the late 1990s, and overtook the Americas a decade later. In contrast to Africa, Europe's population is now in decline, as birth rates are consistently below death rates in many countries, especially in the south and east, resulting in natural population decline. Similarly, the population of the Americas and Asia are expected to go into decline in the second half of this century, and only Oceania's population will still be growing alongside Africa. By 2100, the world's population will have over three billion more than today, with the vast majority of this concentrated in Africa. Demographers predict that climate change is exacerbating many of the challenges that currently hinder progress in Africa, such as political and food instability; if Africa's transition is prolonged, then it may result in further population growth that would place a strain on the region's resources, however, curbing this growth earlier would alleviate some of the pressure created by climate change.

According to the forecast, Africa's total population would reach nearly 2.5 billion by 2050. In 2023, the continent had around 1.36 billion inhabitants, with Nigeria, Ethiopia, and Egypt as the most populous countries. In the coming years, Africa will experience significant population growth and will close the gap significantly with the Asian population by 2100. Rapid population growth The population of Africa has been increasing annually in recent years, growing from around 818 million to over 1.39 billion between 2000 and 2021, respectively. In the same period, the annual growth rate of the population has been constantly set at roughly 2.5 percent, with a peak of 2.62 percent in 2014. The reasons behind this rapid growth are various. One factor is the high fertility rate registered in African countries. In 2021, a woman in Niger had an average of over 6.8 children in her reproductive years, the highest rate on the continent. High fertility resulted in a large young population and partly compensated for the high mortality rate in Africa, leading to fast-paced population growth. High poverty levels Africa’s population is concerned with widespread poverty. In 2024, over 429 million people on the continent are extremely poor and live with less than 2.15 U.S. dollars per day. Globally, Africa is the continent hosting the highest poverty rate. In 2024, the countries of Nigeria and the Democratic Republic of the Congo account for around 21 percent of the world's population living in extreme poverty. Nevertheless, poverty in Africa is forecast to decrease in the coming years.

As of 2023, the total population of Africa was over 1.48 billion. The number of inhabitants on the continent increased annually from 2000 onwards. In comparison, the total population was around 831 million in 2000. According to forecasts, Africa will experience impressive population growth in the coming years and would nearly reach the Asian population by 2100. Over 200 million people in Nigeria Nigeria is the most populous country in Africa. In 2023, the country’s population exceeded 223 million people. Ethiopia followed with a population of around 127 million, while Egypt ranked third, accounting for approximately 113 million individuals. Other leading African countries in terms of population were the Democratic Republic of the Congo, Tanzania, South Africa, and Kenya. Additionally, Niger, the Democratic Republic of Congo, and Chad recorded the highest population growth rate on the continent in 2023, with the number of residents rising by over 3.08 percent compared to the previous year. On the other hand, the populations of Tunisia and Eswatini registered a growth rate below 0.85 percent, while for Mauritius and Seychelles, it was negative. Drivers for population growth Several factors have driven Africa’s population growth. For instance, the annual number of births on the continent has risen constantly over the years, jumping from nearly 32 million in 2000 to almost 46 million in 2023. Moreover, despite the constant decline in the number of births per woman, the continent’s fertility rate has remained considerably above the global average. Each woman in Africa had an average of over four children throughout her reproductive years as of 2021, compared to a world rate of around two births per woman. At the same time, improved health and living conditions contributed to decreasing mortality rate and increasing life expectancy in recent years, driving population growth.

In 2022, Nigeria's population was estimated at around *** million individuals. Demographic projections show that the Nigerian population might experience a constant increase in the next decades. By 2050, it is forecast that the population will grow to over *** million people compared to 2022.

This statistic shows the median age of the population in Nigeria from 1950 to 2100. The median age is the age that divides a population into two numerically equal groups; that is, half the people are younger than this age and half are older. It is a single index that summarizes the age distribution of a population. In 2020, the median age of the Nigerian population was 16.9 years.

Nigerias Einwohnerzahl steigt rasant an und wird für das Jahr 2023 auf geschätzt rund 227,9 Millionen Einwohner:innen geschätzt. Für das Jahr 2024 wird eine Gesamtbevölkerung Nigerias von rund 232,7 Millionen Menschen prognostiziert. Damit hat sich die Gesamtbevölkerung Nigerias in den letzten zehn Jahren um rund 50 Millionen Menschen erhöht. Nigeria verdoppelt die Einwohnerzahl Ein Ende des Bevölkerungswachstums von Nigeria ist bisher nicht absehbar – laut der Bevölkerungsprognosen der Population Division der UN, wird Nigeria bereits im Jahr 2050 die drittgrößte Bevölkerung weltweit aufweisen. Bis dahin wird sich die Gesamtbevölkerung von Nigeria innerhalb von 30 Jahren auf rund 400 Millionen Einwohner verdoppeln. Nigeria in der demographische Übergangsphase Nigeria befindet sich hinsichtlich der demographischen Entwicklung in einer Übergangsphase. Die Fertilitätsrate von Nigeria ist noch sehr hoch, hat ihren Höhepunkt jedoch überschritten und sinkt bereits. Analog zur Geburtenrate sinkt auch die Sterberate langsam und die Lebenserwartung in Nigeria erhöht sich. Obwohl Frauen in Nigeria also zukünftig immer weniger Kinder bekommen werden, wird die Einwohnerzahl des Landes dennoch zunehmen, weil parallel - wegen der steigenden Lebenserwartung - die Sterberate in Nigeria sinkt. Natürliche Bevölkerungsentwicklung oder Migration? Grundsätzlich kann bei der Bevölkerungsentwicklung zwischen dem natürlichen Bevölkerungswachstum und der Zuwachsrate (allgemeines Bevölkerungswachstum) unterschieden werden:natürliches Bevölkerungswachstum

Das natürliche Bevölkerungswachstum ergibt sich aus der Verrechnung von Geburten und Todesfällen.

Zuwachsrate

Bei der Zuwachsrate wird das natürliche Bevölkerungswachstum mit dem Migrationssaldo, also dem Saldo aus Immigration (Einwanderung) und Emigration (Auswanderung) verrechnet.

Zusammenhang

Industrieländer benötigen im Allgemeinen eine Geburtenrate (Fertilitätsrate) von durchschnittlich 2,1 Kindern je Frau, um den Bestand der Population konstant zu halten (Bestandserhaltungsniveau). Für ein positives Bevölkerungswachstum wird dementsprechend eine höhere Geburtenrate oder ein positiver Migrationssaldo benötigt.

Mitte des Jahres 2023 ist Indien mit rund 1,44 Milliarden Einwohner:innen das Land mit der weltweit größten Bevölkerungszahl. China steht im Jahr 2023 mit rund 1,42 Milliarden Einwohner:innen weltweit auf Platz, gefolgt von den USA mit einer Gesamtbevölkerung von rund 343,5 Millionen Menschen. Im Jahr 2023 hat Indien China als bevölkerungsreichstes Land abgelöst. Im Laufe der kommenden Jahrzehnte werden einige neue Länder in die Liste der 10 bevölkerungsreichsten Länder der Welt hinzukommen (z.B. DR Kongo oder Tansania) und andere Länder werden aus den Top 10 herausfallen (z.B. Russland). Im Jahr 2100 wird laut der Prognose Indien mit rund 1,5 Milliarden Einwohner:innen der bevölkerungsreichste Staat der Welt sein. Chinas Gesamtbevölkerung wird sich hingegen bis zum Jahr 2100 nahezu halbieren auf rund 633,4 Millionen Bürger:innen. Die Statistik zeigt die zehn Länder mit der jeweils größten Bevölkerung in den Jahren 1950, 2000, 2020 und 2023 sowie entsprechende Prognosen für 2030, 2050 und 2100.
