France’s mainland population (not including its oversears territories) will pass the 70 million mark by mid-century, reaching 72 million for the first time ever in 2050, according to a French study published on Wednesday (see below).
That’s a 13 percent increase in less than 40 years, from today’s population of 63.9 million, said the biennial ‘Population of the World’ study by INED, France’s National Institute for Demographic studies.
France crossed the 60 million barrier in 2004, and back in the middle of last century, 1950, was home to just 42 million people.
The data also revealed that life expectancy for women in France is now 85, while French men can expect to live to 79 years of age.
As for the population of rest of the world, INED predicts that global population will rise to 9.7 billion in 2050 from the current level of 7.1 billion and India will overtake China as the world's most populous nation.
INED also forecast there would be 10 to 11 billion people on the planet by the end of the century.
The projections ran parallel to forecasts by the United Nations, the World Bank and other prominent national institutes.
A UN study in June said the global population would swell to 9.6 billion in2050 and the number of people aged 60 and above would catapult from 841 million now to two billion in 2050 and nearly three billion in 2100.
INED said Africa would be home to a quarter of the world's population in 2050 with 2.5 billion people, more than double the current level of 1.1 billion.
Gilles Pison, the author of the report, said the prevailing fertility rate in Africa was around 4.8 children per woman – far higher than the global average of 2.5.
The Americas will breach the one-billion mark in 2050 with 1.2 billion inhabitants against 958 million at present.
And Asia's population will increase from 4.3 billion to 5.2 billion in 2050, INED projected.
The world's most populous nations are currently China with 1.3 billionpeople; followed by India (1.2 billion); the United States (316.2 million); Indonesia (248.5 million) and Brazil (195.5 million).
But in 2050, India will take pole position with 1.6 billion people, with China in second place at 1.3 billion.
Nigeria, Africa's most populous country, will outstrip the United States with a population of 444 million against a projected 400 million Americans in the middle of the century.
Here is Wednesday's report itself, from the Institut national d'études démographiques.
