How the numbers work: Rather than multiplying global averages together — which gives absurdly small results and ignores the fact that blessings tend to cluster — this tool splits the world into 11 regions and uses realistic per-region rates for each attribute. If you have clean water, you probably also have electricity. The intersection counts reflect that reality. They're honest estimates, not precise census figures. Use them as perspective.
