The world’s population is growing older and growing at a slower pace but is expected to rise from the current 7.7 billion to 9.7 billion in 2050, the United Nations said on Monday.
The Department of Economic and Social Affairs of the UN Population Division has released a new report that the world’s population may peak at the end of the century, at around 11 billion people.
But Population Division director John Wilmoth warned that this result, since 2100 is still within decades’ range, “is uncertain and that the peak may happen sooner or later and at a lower or higher level of total population”.
New population projections indicate that nine countries will account for more than half of projected population growth by 2050. In descending order of expected increase, India, Nigeria, Pakistan, Congo, Ethiopia, Tanzania, Indonesia, Egypt, and United America.
In sub-Saharan Africa, the population is expected to double by 2050.
Deputy Secretary-General for Economic and Social Affairs Lu Zhenmin said in a statement: “Many of the fastest growing populations are in countries that are the poorest, where population growth poses additional challenges to the effort to eradicate poverty “, promote gender equality and improve health care and education.
The document confirms that the world’s population is aging due to increasing life expectancy and declining levels of fertility.
