Of the world's 20 poorest states, the Democratic Republic of the Congo spends the least per citizen on health care — $19 per person annually.
And in Sierra Leone, the highest health spender among those states south of the Sahara, it's over triple — $66 per capita.
That's still just a fraction of how much the world's wealthiest countries spend on each of their residents' health. In the United States, the number is nearly $10,000. Half of the 20 richest countries spend at least $5,000 per person.
