If we could shrink the earth's population to a village of precisely 100 people, with all the existing human ratios remaining the same, it would look something like the following:

There would be:
-57 Asians
-21 Europeans
-14 from the Western Hemisphere, both north and south
-8 Africans
-52 would be female
-48 would be male
-70 would be non-white
-30 would be white
-70 would be non-Christian
-30 would be Christian
-89 would be heterosexual
-11 would be homosexual
-6 people would possess 59% of the entire world's wealth and all 6 would be from the United States.
-80 would live in substandard housing
-70 would be unable to read
-50 would suffer from malnutrition
-1 would be near death; 1 would be near birth
-1 (yes, only 1) would have a college education
-1 would own a computer

When one considers our world from such a compressed perspective, the need for acceptance, understanding and education becomes glaringly apparent.
