In yet another illustration of China's and India's enormous populations, Reddit recently surfaced the above population map, which claims more than half the world’s people live within a circle superimposed over a section of Asia.

Amazingly, the numbers check out. The world population, according to the U.S. Census Bureau, is roughly 7,083,460,000. The countries in the circle are ...

China: 1,349,585,838 people (per the Census again)
India: 1,220,800,359
Indonesia: 251,160,124
Bangladesh: 163,654,860
Japan: 127,253,075
Philippines: 105,720,644
Vietnam: 92,477,857
Thailand: 67,448,120
Burma: 55,167,330
South Korea: 48,955,203
Nepal: 30,430,267
Malaysia: 29,628,392
North Korea: 24,720,407
Taiwan: 23,299,716
Sri Lanka: 21,675,648
Cambodia: 15,205,539
Laos: 6,695,166
Mongolia: 3,226,516
Bhutan: 725,296

… which adds up to a grand total of 3,637,830,357, or roughly 51.4 percent of the global population. (The circle also appears to include parts of Russia and Pakistan, which I haven't included, and may have cut off a bit of northwest China.)

Asia’s population dominance is not a new thing: According to this neat NPR video on population growth, "most people lived in China, India and the rest of Asia" around the year 1000, too. But since population growth has gotten so fast, Asia is now expanding on an entirely different scale. By 2050, the U.N. predicted last year, 3.3 billion people will live just in Asia's cities.
