Top 10 Most Countries by Kid Population

How to count the world population?
There's no way to know exactly how many people are alive at any given moment, and the true date that humanity's ranks will surpass 7 billion could come in the weeks or months before or after Oct. 31. Nonetheless, the UN's guess is the best there is.

How do they make it? By synthesizing a mind-boggling array of data.

According to a chief analyst in the UNPD, its population estimate relies on fertility, mortality and migration information gathered by government censuses, independent demographic and health surveys, vital registers (official birth and death records), the World Health Organization, the UN High Commission on Refugees, and academic studies. UN analysts revise their country and world population curves every five years to account for any new data gathered by those entities since their last revision; they completed the current population projections earlier this year.
