According to a recent United Nations report, the world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100.
Roughly 83 million people are expected to be added to the world's population every year, even though fertility levels are assumed to continue declining.
Among the 10 largest countries worldwide, Nigeria is growing the most rapidly. The population of Nigeria -- currently the world’s seventh largest -- is projected to surpass that of the United States and to become the third-largest country in the world shortly before 2050.
