What Percentage of the World Is Black? Population questions that intersect with race require careful handling of definitions, data sources, and context.
This article uses “Black and African” to refer to people of Sub-Saharan African descent, both on the continent and in diaspora communities globally — the framework used by the United Nations and major demographic research bodies.
What Percentage of the World Is Black
Approximately 17.9 percent of the world’s population — roughly 1.4 billion people out of a global total of 8.1 billion — is Black or of African descent as of 2024. Sub-Saharan Africa accounts for the largest share of this figure at 1.2 billion people, representing 14.7 percent of the global population on its own.
The Black diaspora living outside Africa — primarily in the Americas, Europe, and the Caribbean — adds another 250 million people to the total.
Where the Population Lives
The geographic distribution is heavily concentrated in Africa, with diaspora populations spread across multiple continents:
| Region | Population | Share of Global Black Population | Annual Growth Rate |
|---|---|---|---|
| Sub-Saharan Africa | 1.202 billion | 84.3% | 2.4% |
| Americas (diaspora) | 142 million | 10.0% | 0.8% |
| Caribbean | 34 million | 2.4% | 0.4% |
| Europe (diaspora) | 18 million | 1.3% | 1.2% |
| Other regions | 29 million | 2.0% | 1.5% |
Within Sub-Saharan Africa, East Africa is the most populous subregion at 492 million, followed by West Africa at 435 million, Central Africa at 203 million, and Southern Africa at 72 million. East Africa also grows fastest at 2.7 percent annually.
The Largest Black-Majority Nations
Five countries account for 41 percent of Africa’s total population:
Nigeria leads significantly with 223 million people in 2024 — the sixth most populous country on earth regardless of racial composition. Ethiopia follows at 126 million, then the Democratic Republic of Congo at 102 million, Tanzania at 67 million, and South Africa at 60 million.
Population density varies dramatically across the continent. Rwanda reaches 525 people per square kilometer on the mainland, Nigeria 246. At the other extreme, Botswana and Namibia fall below 5 people per square kilometer due to desert geography.
The Diaspora in Detail
Brazil hosts the largest Black population outside Africa — 120 million people identified as Black or mixed race in the 2022 census, representing 56 percent of Brazil’s total population. This makes Brazil second only to Nigeria globally in Black population size.
The United States follows with 47.9 million Black or African American residents as of 2023, comprising 14.4 percent of the US population and reflecting a 10.8 percent increase from 2010. Haiti’s population is 95 percent Black at 11.4 million people. Jamaica stands at 92 percent.
In Europe, France has the largest estimated Black population at 5 to 6 million people, though French law prohibits official racial statistics so the figure relies on estimates.
The United Kingdom recorded 2.4 million Black residents in the 2021 census — 4 percent of the population. Germany reached approximately 1 million and Italy 800,000, with both populations growing primarily through Sub-Saharan African and Caribbean immigration between 2000 and 2024.
How Fast This Population Is Growing
The scale of Africa’s demographic growth is genuinely striking in historical context. Between 2000 and 2024, Africa’s total population rose from approximately 812 million to 1.4 billion — a 72 percent increase in 24 years. Over the same period, global population grew by 33 percent. Africa outpaced world population growth by more than double.
The continent added 588 million people between 2000 and 2024 — more people than currently live in the entire European Union.
The annual pace has been accelerating. The 2000-2010 decade saw an average of 23.4 million new residents per year. The 2010-2020 decade increased to 27.8 million annually. From 2020 to 2024, despite the COVID-19 pandemic, Africa added 116 million people at an average of 29 million per year.
Age Structure: The Youngest Major Population on Earth
Africa’s demographic profile is dramatically younger than any other major world region. The median age across the continent is 19.7 years, compared to a global median of 30.5 years. In Europe and much of Asia, median ages now exceed 40 years.
Sub-Saharan Africa records the most extreme youth distribution: 43 percent of the population is under 15 years old. Globally that figure is 25 percent.
Nigeria’s median age is 18.6 years. Ethiopia’s is 19.8. These figures have profound implications for future population growth — a population where nearly half the people have not yet reached reproductive age will continue expanding substantially regardless of changes in fertility rates.
| Age Group | Africa | Global Average |
|---|---|---|
| Under 15 | 43% | 25% |
| 15-24 | 19% | 15% |
| 25-54 | 30% | 41% |
| 55-64 | 5% | 9% |
| 65 and over | 3% | 10% |
Urbanization: A Historic Threshold Crossed
In 2024, Africa’s urban population reached 608 million people — 50.6 percent of the continent’s total. This marked the first time in African history that urban residents outnumbered rural ones.
Lagos became Africa’s largest city with 15.4 million residents, growing at 3.2 percent annually. Kinshasa follows closely at 15.1 million, growing even faster at 4.1 percent per year. Luanda in Angola reaches 8.9 million at 3.9 percent annual growth. Johannesburg and Nairobi round out the top five at 6.2 million and 5.1 million respectively.
This urban transition is reshaping economic geography, infrastructure demands, and political dynamics across the continent in ways that will compound over the coming decades.
Projections Through 2050 and 2100
United Nations projections carry substantial uncertainty at longer time horizons but establish a clear directional picture.
By 2050, Africa’s population is projected to reach 2.5 billion — adding another 1.3 billion people in 26 years and raising Africa’s share of global population to approximately 25.6 percent.
By 2100, the continent could hold 4.3 billion people, representing 39 percent of a projected global population of 11 billion. Nigeria alone may reach 733 million by 2100, which would exceed China’s projected population at that time.
Regional growth within Africa will not be uniform. East Africa’s population could triple from 492 million in 2024 to 1.5 billion by 2100. West Africa could reach 1.2 billion. Southern Africa, which has lower fertility rates, is projected to grow more modestly from 72 million to 140 million over the same period.
Context for Interpreting These Numbers
Racial categorization is not uniformly defined across countries or census systems. Brazil’s racial self-identification framework differs substantially from the US Census approach. France does not collect racial data officially. Many African countries use ethnic rather than racial categories in their census work.
The 1.4 billion figure requires aggregating across these different national methodologies, which introduces measurement uncertainty.
The diaspora estimate of 250 million depends on how mixed-race individuals identify and are classified — a question with different answers in different national contexts.
What the data does establish clearly and consistently: Black and African populations represent a substantial and rapidly growing share of global humanity, with the demographic center of gravity shifting toward Sub-Saharan Africa at a pace that will continue reshaping global population geography throughout the 21st century.
