The UN’s recent “World Population Prospects” report predicts that in little more than a decade the world population will likely hit 8.5 billion people and nearly 10 billion by 2050, and then the world population is expected to peak at around 11 billion by 2100.
The United Nations predicts that more than half of the growth between now and 2050 will take place in only nine countries, listed in order from most to least population growth: India, Nigeria, Pakistan, the Democratic Republic of Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States.
India is expected to be the most-populated country by 2027, overtaking China. China’s population is projected to decline by 2.2% between now and 2050.
Sub-Saharan Africa is expected to double its population by 2050, adding 1 billion people.
In 2018, for the first time in human history, people 65 years and older outnumbered children under 5 years old.
