For the primary time in trendy historical past, the world’s inhabitants is predicted to just about cease rising by the top of this century, due largely to falling international fertility charges, in line with a Pew Analysis Heart evaluation of latest knowledge from the United Nations.
By 2100, the world’s inhabitants is projected to succeed in roughly 10.9 billion, with annual development of lower than 0.1% – a steep decline from the present price. Between 1950 and right this moment, the world’s inhabitants grew between 1% and a pair of% every year, with the variety of individuals rising from 2.5 billion to greater than 7.7 billion.
Listed here are 11 key takeaways from the UN’s “World Inhabitants Prospects 2019”:
The worldwide fertility price is predicted to be 1.9 births per lady by 2100, down from 2.5 right this moment. The speed is projected to fall beneath the substitute fertility price (2.1 births per lady) by 2070. The substitute fertility price is the variety of births per lady wanted to take care of a inhabitants’s measurement.
The world’s median age is predicted to extend to 42 in 2100, up from the present 31 – and from 24 in 1950. Between 2020 and 2100, the variety of individuals ages 80 and older is predicted to extend from 146 million to 881 million. Beginning in 2073, there are projected to be extra individuals ages 65 and older than below age 15 – the primary time this would be the case. Contributing components to the rise within the median age are the rise in life expectancy and falling fertility charges.
Africa is the one world area projected to have sturdy inhabitants development for the remainder of this century. Between 2020 and 2100, Africa’s inhabitants is predicted to extend from 1.3 billion to 4.3 billion. Projections present these beneficial properties will come principally in sub-Saharan Africa, which is predicted to greater than triple in inhabitants by 2100. The areas that embody america and Canada (Northern America) and Australia and New Zealand (Oceania) are projected to develop all through the remainder of the century, too, however at slower charges than Africa. (This evaluation makes use of regional classifications from the UN and should differ from different Pew Analysis Heart experiences.)
Europe and Latin America are each anticipated to have declining populations by 2100. Europe’s inhabitants is projected to peak at 748 million in 2021. The Latin America and Caribbean area is predicted to surpass Europe in inhabitants by 2037 earlier than peaking at 768 million in 2058.
The inhabitants of Asia is predicted to extend from 4.6 billion in 2020 to five.3 billion in 2055, then begin to decline. China’s inhabitants is predicted to peak in 2031, whereas the populations of Japan and South Korea are projected to say no after 2020. India’s inhabitants is predicted to develop till 2059, when it would attain 1.7 billion. In the meantime, Indonesia – probably the most populous nation in Southeastern Asia – is projected to succeed in its peak inhabitants in 2067.
Within the Northern America area, migration from the remainder of the world is predicted to be the first driver of continued inhabitants development. The immigrant inhabitants in america is predicted to see a web improve of 85 million over the following 80 years (2020 to 2100) in line with the UN projections, roughly equal to the overall of the following 9 highest nations mixed. In Canada, migration is more likely to be a key driver of development, as Canadian deaths are anticipated to outnumber births.
Six nations are projected to account for greater than half of the world’s inhabitants development by way of the top of this century, and 5 are in Africa. The worldwide inhabitants is predicted to develop by about 3.1 billion individuals between 2020 and 2100. Greater than half of this improve is projected to come back from Nigeria, the Democratic Republic of the Congo, Tanzania, Ethiopia and Angola, together with one non-African nation (Pakistan). 5 African nations are projected to be on the planet’s prime 10 nations by inhabitants by 2100.
India is projected to surpass China because the world’s most populous nation by 2027. In the meantime, Nigeria will surpass the U.S. because the third-largest nation on the planet in 2047, in line with the projections.
Between 2020 and 2100, 90 nations are anticipated to lose inhabitants. Two-thirds of all nations and territories in Europe (32 of 48) are anticipated to lose inhabitants by 2100. In Latin America and the Caribbean, half of the area’s 50 nations’ populations are anticipated to shrink. Between 1950 and 2020, in contrast, solely six nations on the planet misplaced inhabitants, as a result of a lot increased fertility charges and a comparatively youthful inhabitants in previous a long time.
Africa is projected to overhaul Asia in births by 2060. Half of infants born worldwide are anticipated to be born in Africa by 2100, up from three-in-ten right this moment. Nigeria is predicted to have 864 million births between 2020 and 2100, probably the most of any African nation. The variety of births in Nigeria is projected to exceed these in China by 2070.
In the meantime, roughly a 3rd of the world’s infants are projected to be born in Asia by the top of this century, down from about half right this moment and from a peak of 65% within the 1965-70 interval.
The Latin America and Caribbean area is predicted to have the oldest inhabitants of any world area by 2100, a reversal from the twentieth century. In 1950, the area’s median age was simply 20 years. That determine is projected to greater than double to 49 years by 2100.
This sample is clear when particular person nations within the area. For instance, in 2020, the median ages of Brazil (33), Argentina (32) and Mexico (29) are all anticipated to be decrease than the median age within the U.S. (38). Nevertheless, by 2100, all three of those Latin American nations are projected to be older than the U.S. The median age will probably be 51 in Brazil, 49 in Mexico and 47 in Argentina, in contrast with a median age of 45 within the U.S. Colombia is predicted to bear a very stark transition, with its median age greater than tripling between 1965 and 2100 – from 16 to 52.

It’s anticipated to be decrease in 2100 (54). By that point, the nation with the best median age is predicted to be Albania, with a median age of 61.
Correction: This submit has been up to date to make clear that India is predicted to develop into the world’s most populous nation by 2027. By 2059, its inhabitants is projected to peak at 1.7 billion.
Word: The UN projections for the longer term inhabitants are primarily based on assumptions about doubtless future modifications in key demographic indicators, together with fertility, life expectancy and migration. There may be uncertainty relating to particular estimates. This evaluation makes use of the medium variant for future dates, which takes the midpoint of doubtless outcomes.
