Principles of Macroeconomics / Unit 16 MAC 1503 short lesson, about 20 seconds
The Four Income Groups
Captions available
The idea
The World Bank sorts economies into four tiers by income per person: low, lower-middle, upper-middle and high. It sets the thresholds and updates them every year.
In practice
The middle tiers hold most of the world's people; the high tier holds most of the income.
Where people slip
The course voices no threshold, because the anchor gives four inconsistent sets.
