385: Demographic Oddity


Can you explain how this is possible? Qatar is only 23.5% women?

Before we get into these issue-specific statistics, we can see in basic demographics something that’s different about living in Saudi Arabia as a woman: Only 42.5 percent of the population is female. There are only five countries in the world (for which we have data) with a smaller percentage of female residents, according to the World Bank: Qatar, where just 23.5 percent of the population is female, the United Arab Emirates (29.9 percent female), Oman (36.4 percent), Bahrain (37.8 percent) and Kuwait (40.2 percent).

If you want to see a reasonable explanation, go to the

Describe the squares and their sizes compared to the circle.

1. If you were to calculate distances (radii, side lengths) or areas, what given information would you like to start with and what would you like to solve for?
  • What "givens -- answer" path would be easiest?
  • What "givens -- answer" path would be difficult?
