But the positives in the report were that India, Pakistan and Bangladesh have shown declining fertility rates and improved life expectancy levels
India will outstrip China to have the world's largest population in the next seven years, according to a UN report.
The UN report, entitled 'The World Population Prospects: The 2017 Revision', stated both countries would have roughly 1.44 billion people in 2024, with India slightly ahead.
But India's population is estimated to grow thereafter, whereas China will remain steady till the 2030s and then expected to decline.
As for India, its population will surge to 1.5 billion in 2030 and 1.66 billion in 2050.
The study also stated that the fertility rates of Indian women have halved in the last four decades. From 4.97 live births per woman, the average number has gone down to 2.3, and will incrementally slide till 2100.
Pakistan has also declined from 6.6 live births per woman in 1975 to 3.38 in 2015. Bangladesh fared even better -- from 6.63 in 1975 to 2.07 in 2015.
The other upside has been India's growing life expectancy rates from 59.2 in 1990-95 to 68.9 years of age in 2015-20. By the turn of this centure, the rate would go up to 81.
Life expectancy rates for Bangladesh have gone up from 60 in 1995 to 73 in 2015; Pakistan improved from 60.8 to 66.7 in the same period.
At the moment, China -- with a population of 1.4 billion -- and India (1.3 billion) comprise 19 and 18 per cent of world's total population.
The current world population is 7.6 billion but will add another billion people by 2030. By 2100, the world population will be a little over 11 billion.
