They will continue to have mass illegal migration even 20 yrs from now. Including intercontinental migration to South Africa and nearby other countries in Africa like South Africa will be in further danger to those countries less they can put up their own borders or manage population numbers with education.
As bad as it is now without population control by prevention, problems that may cause mass illegal immigration in the future to countries trying to keep their population in control. In 1900 the population of the continent of Africa was a minority only 9 percent until foreign aid and science from advanced countries improved survival numbers of children under the age of 5 by disease and starvation by colonial forces that increased their survival numbers.
A demographic overview of global and regional population trends, focusing specifically on the historical and projected growth of Africa.
Global Population Overview (1900)
In 1900, the world population was approximately 1.6 billion people. The most populous regions were Asia (about 947 million) and Europe (about 408 million). Due to imperial and colonial rule, borders looked very different, and major populations included:
– Chinese Empire (Qing Dynasty): ~400,000,000 to 430,000,000
– British India: ~280,000,000 to 290,000,000
– Russian Empire: ~132,000,000 to 136,000,000
– United States: 75,994,575
– German Empire: ~56,000,000
– Austro-Hungarian Empire: ~45,000,000
– Japan: ~44,000,000 to 45,000,000
– United Kingdom: ~41,000,000
– French Empire: ~40,000,000 (excluding overseas colonies)
– Italian Peninsula: ~32,000,000
– Ottoman Empire: ~19,000,000
– Mexico: ~13,600,000
Africa’s Demographic Evolution
In 1900, Africa’s population was estimated at 133 to 140 million people, accounting for roughly only 9% of the global total. The largest regional populations tracked by colonial divisions included British Africa (~44 million, including 10 million in Egypt and 10 million in Nigeria), French Africa (~31 million, including 4.4 million in Algeria), Belgian Africa (~8 million in the Congo Free State), German Africa (~10 million), Portuguese Africa (~4 million in Angola), and Ethiopia (~4 million).
Following incoming advancements in agriculture, medicine, and living standards, Africa has become the fastest-growing region globally. In 2026, the continent’s total population is estimated at 1,584,985,259. The top 10 most populous nations are:
1. Nigeria: 242,431,832
2. Ethiopia: 138,902,185
3. Egypt: 120,101,175
4. DR Congo: 116,452,162
5. Tanzania: 72,563,780
6. South Africa: 65,453,084
7. Kenya: 58,636,412
8. Sudan: 53,282,719
9. Uganda: 52,761,469
10. Algeria: 48,028,334
Future Projections and Challenges (2050)
By 2050, Africa’s population is projected to reach approximately 2.5 billion, meaning roughly one in four people on Earth will be African. This rapid demographic expansion presents several critical structural challenges:
– Unprecedented Urbanization: Urban populations are expected to double to 1.4 billion, straining housing and public infrastructure in major hubs like Lagos, Kinshasa, and Nairobi.
– Workforce Expansion: Africa will possess the world’s largest workforce within the next decade. However, 82% of current workers are in the informal sector, highlighting the urgent need for quality job creation to prevent social instability.
– Food and Resource Scarcity: To meet consumption needs, agricultural production must scale significantly, requiring an estimated additional 120 million hectares of land, which poses risks for deforestation and water ecosystems.
– Social Services Pressure: By the 2040s, the continent will account for two out of every five global births, placing immense pressure on governments to fund and expand healthcare and education systems.
