Measuring Global Inequality
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Global inequality is measured by national income per person, but averages conceal distribution, so a measure of spread is required alongside them.
Show
Two nations with identical average income can differ entirely in how that income is spread.
Watch for
Read a national average as a mean, and ask immediately for the distribution behind it.
