Practice question · Multiple choice
The Gini coefficient reduces an entire income distribution to a single number between zero and one. What does a sociologist give up in accepting that summary?
Hints
- Ask whether two countries with the same coefficient must have the same distribution.
- A gap concentrated at the top and one concentrated at the bottom can summarise identically.
Show the answer
A. Details on where inequality sits, since distinct distributions can share a score
Why
A single statistic cannot distinguish a society with a detached elite from one with an excluded bottom, and the two call for entirely different policies. That is why Gini coefficients are normally reported alongside decile ratios or top income shares, which say where the distance is.
