My household just received the latest issue of National Geographic, which contains a massive pull-out poster showing “a composite face of the world’s most typical person” as the total world population nears seven billion people.
The portrait is fascinating to ponder, but it’s the poster’s back side featuring a comparative chart of the world that presents some striking differences and disparities. The mapmakers have categorized the world’s populations into four groups of annual income-earners: low-income ($995 or less), lower middle ($995-$3,945), upper middle ($3,946-$12,195), and high (more than $12,196). Then they highlight selected statistics — birth rates, number of cars, fertility and net migration rates, and others — and show the differences among the four groups through more data.
The father of two boys under the age of five, I found the disparity among the fatality rates of children age five and under absolutely gut-wrenching: low-income families see 120 deaths per 1,000 live births whereas high-income families only experience seven deaths. It’s tragic, but even bumping those low-income earners over the $1,000 dollar threshold into the lower middle class halves the number of deaths.
