Great Gatsby curve

The Great Gatsby Curve is a graph that shows how inequality of wealth and income is related. It looks at the differences between people who have a lot of money compared to people who don't.
The graph has two lines. The top line shows the amount of money that people with the highest incomes have. The bottom line shows how much money people with the lowest incomes have. The higher up the line, the more money those people have. The farther apart the two lines are, the more inequality there is in a society.
