What is the Gini Coefficient?
The Lorenz Curve plots the cumulative box-office earnings of the top 100 movies.
A straight diagonal line represents an ideal, equal distribution. The area between this ideal line and the actual curve (often bowing away) is filled in red to highlight the disparity.
To calculate the Gini coefficient, this red area is divided by the total area under the diagonal line. The resulting Gini coefficient ranges from 0 to 1: a coefficient of 0 would mean no red area and perfect equality in earnings, while a coefficient of 1 would indicate that one movie hauled in all the earnings, making the red area as large as possible.

Inequality Over Time
Gini Coefficient
The data on the Gini coefficient for movie box office returns from 1980 to 2023 indicates a complex picture of evolving inequality. Prior to the COVID-19 pandemic, the Gini coefficient generally fluctuated within a moderate range of 0.35 to 0.54, signaling a relatively stable yet gradually increasing inequality in box office earnings.
However, a sharp and pronounced uptick is evident from 2020 onwards, soaring to levels above 0.70. This escalation likely exacerbated pre-existing trends and could potentially signify a permanent structural change in the industry's box office dynamics.
