Population Projections For India
In 2023, India first topped the UN list of most populous countries since it started collecting population data in 1950.
According to the UN report, by 2050, India's population is expected to rise to 1.66 billion, while China's population will dip to 1.31 billion. The report also stated that the global population is growing at its slowest rate since 1950, having fallen under one per cent in 2020. Life expectancy at birth for males in India is 71, while for females it is 74 years.
UN projections estimate that the country's population is expected to grow for the next three decades after which it will begin declining.
According to the United Nations Population Fund (UNFPA), the size of elderly population in India will nearly double to touch 192 million by 2030, largely in southern and western states. By 2050, every fifth Indian will be an elderly person. The health and economic security of the elderly will need to gain primacy, the UNFPA said.
