I just read this in an Uncle John's Bathroom Reader, so take it with a grain of salt, but I found it fascinating all the same. ;)
If you could shrink the world down to 100 people - keeping the same ratios - there would be:
51 females, 49 males
57 Asians, 21 Europeans (14 from the Americas), and 8 Africans
70 nonwhites, 30 whites
70 non-Christians, 30 Christians
50% of the wealth would be in the hands of 6 people - all in the US
80 living in substandard housing
70 would be illiterate
50 would be suffering from malnutrition
1 person near death, one near birth
1 with a college education
Not one with a computer
This particular edition was published in 2004, so like I said, grain of salt. ;)
If you're not familiar with the Uncle John's Bathroom Reader line, I HIGHLY recommend them all for interesting bits of trivia and all kinds of knowledge you never learned in school. :)
