World population projected to reach 9.7 billion by 2050

The current world population of 7.3 billion is expected to reach 8.5 billion by 2030, 9.7 billion in 2050 and 11.2 billion in 2100, according to a new UN DESA report, “World Population Prospects: The 2015 Revision”, launched today. India expected to become the largest country in population size, surpassing China around 2022, while Nigeria could surpass the United States by 2050

The UN projects world population rising from about 7.7 billion (2019 estimate) to 9.7 billion in 2050, possibly peaking near 11 billion late in the century, though the UN's Population Division director says that peak "is not certain"^[2][3]
More than half of the growth to 2050 comes from nine countries: India, Nigeria, Pakistan, DR Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States; sub-Saharan Africa's population nearly doubles^[2][3]
India is projected to overtake China (by 2027 in the 2019 revision), while China's population falls by more than two percent by 2050^[3]
Fertility fell from 3.2 births per woman in 1990 to 2.5 in 2019 and is projected at 2.2 by 2050, against 2.1 needed for replacement^[2][3]
27 countries or areas lost at least one percent of population since 2010; 55 countries are projected to shrink by 1% or more by 2050^[2][3]
Life expectancy is expected to reach 77.1 years in 2050, up from 72.6 now^[3]
