According to new data, the population of India is expected to reach 1 billion 425 million 775 thousand 850 people by the end of April.
Last week, a different UN team predicted that India would overtake China by the middle of this year.
Asian countries have accounted for more than a third of the global population for over 70 years.
“China will soon lose its long-held status as the world’s most populous country,” the UN Department of Economic and Social Affairs (DESA) said in a statement.
“Due to uncertainty over population estimation, the specific date when India is expected to surpass China in population size is approximate and subject to revision,” it said.
The UN Population Fund said last week that India will have a population of 2.9 million more than China by mid-2023.
China’s birth rate has fallen recently, as its population declined last year for the first time since 1961.
DESA said China’s population could drop below 1 billion before the end of the century.
In contrast, India’s population is expected to continue to increase for several decades,” he added.
