A few more:

If you can drink a glass of clean water out of the tap without fear of disease, you are doing better than 800 million people;
If you have a daughter in school for more than 5 years, she is doing better than 87% of the female children in the world.
If you have a son in school for more than 5 years, he is doing better than 65% of the male children in the world.
