7 billion people in the world?

Although the number given above seems very precise, it is important to remember that it is just an estimate. It simply isn't possible to be sure exactly how many people there are on the earth at any one time, and there are conflicting estimates of the global population in 2013.

The United States Census Bureau estimates there is one birth every 8 seconds and one death every 12 seconds, with a net gain of one person on earth every 14 seconds.

Map of the world if each country was the same relative size as its population:

Some, including the UN, believe that a population of 7 billion was reached in October 2011. Others, including the US Census Bureau and World Bank, believe that the total population of the world reached 7 billion in 2012, around March or April.
