Measuring Global Inequality
Captions available
The idea
Global inequality is measured by national income per person, but averages conceal distribution, so a measure of spread is required alongside them.
In practice
Two nations with identical average income can differ entirely in how that income is spread.
Where people slip
Read a national average as a mean, and ask immediately for the distribution behind it.
