Population and Stuff

According to Wolfram Alpha, 31 of the world's 50 most populous cities are in China. China contains almost a fifth of the world's population.

Macau is the world's densest country, with fifty three thousand people every square mile, while Greenland is the sparsest (with one person every 14.5 square miles).

The Vatican and the Pitcairn Islands are the most Christian countries, while Somalia is the least. Morocco is the most Muslim country, and Israel is the most Jewish country.

4.3 people are born every second (on average), while 1.8 people die. This means we have a net gain of 2.5 people per second.

The world's population has quadrupled in the 20th century, and yet is has also declined in the 14th century (due to Black Death).
