The world’s population is projected to reach 8 billion on 15 November 2022 from an estimated 2.5 billion people in 1950. It took around 37 years since 1950 for human numbers to double, surpassing 5 billion inhabitants in 1987. Thereafter, it is estimated that more than 70 years will be required for the global population to double again. The latest projections by the United Nations suggest that the global population could grow to around 8.5 billion in 2030, 9.7 billion in 2050 and 10.4 billion in 2100.
More than half of the projected increase in the global population between 2022 and 2050 is expected to be concentrated in just eight countries: the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and the United Republic of Tanzania.
