The world’s population will increase to 9.7 billion by 2050, going up by 2 bn from the earlier 7.7 bn, shows a new United Nations report launched on Monday.
India is projected to overtake China as the world’s most populous country in next 8 years, according to the report. The global fertility rate, which fell from 3.2 births per woman in 1990 to 2.5 in 2019, will decline further to 2.2 in 2050. India’s current total fertility rate stands at 2.2 births per woman.
Nine countries will make up more than half of the projected growth of the global population between now and 2050: India, Nigeria, Pakistan, the Democratic Republic of the Congo, Ethiopia, the United Republic of Tanzania, Indonesia, Egypt and the United States of America.
The population of sub-Saharan Africa is projected to double by 2050, up 99%.
