With nearly 1.5 billion inhabitants, India will emerge as the most populous country in the world in 2017, overtaking China, according to United Nations population data. The world’s population is projected to increase by another 2 billion people by 2050 — from 7.7 billion currently to 9.7 billion in 2050, and, by the end of the century, the planet will have to sustain around 11 billion.
China, with 1.43 billion people in 2019, and India, with 1.37 billion, have long been the two most populous countries of the world, comprising 19 and 18 percent, respectively, of the global total in 2019.
Dynamic Shifts: In China, the population is expected to shrink by as much as 2.2% or 31.4 million by 2050, while the population of India is projected to grow by 273 million. Following the India-China re-ordering in 2027, the ranking of the five largest countries is projected to remain the same until the end of the century.
Most of Europe is shrinking and by the end of the century, it’s expected to decrease by 120 million inhabitants, from close to 750 million today to about 630 million. Italy alone is likely to drop by 20 million inhabitants and Germany by nine million. The United Kingdom is the main European exception. It is expected to increase its population by 10 million people.
