U.N. experts predicted last year India would have a population of 1.412 billion in 2022 though they did not expect the South Asian nation to overtake China until this year.

China's fourth quarter economic growth also slumped to one of its worst levels in nearly half a century as the country was hit hard by strict COVID curbs and a real estate market slump.
