According to a story posted on the United Nations website this week, the world population is projected to reach 9.6 billion by the year 2050.

According to the story posted on the UN website:

The current world population of 7.2 billion is projected to increase by 1 million over the next 12 years and reach 9.6 billion by 2050, according to a United Nations report launched this week, which points out that growth will be mainly in developing countries, with more than half in Africa.

“Although population growth has slowed for the world as a whole, this report reminds us that some developing countries, especially in Africa, are still growing rapidly,” said the Under-Secretary-General for Economic and Social Affairs, Wu Hongbo in a press release on the report.

The report, World Population Prospects: the 2012 Revision, notes that the population of developed regions will remain largely unchanged at around 1.3 billion from now until 2050. In contrast, the 49 least developed countries are projected to double in size from around 900 million people in 2013 to 1.8 billion in 2050.

The report notes that India is expected to become the world’s largest country, passing China around 2028, when both countries will have populations of 1.45 billion. After that, India’s population will continue to grow and China’s is expected to start decreasing. Meanwhile, Nigeria’s population is expected to surpass that of the United States before 2050. Europe’s population is projected to decline by 14 percent, the report states.

1. China - 1,349,585,838
