CORE DEFINITION

A graphical method describing the relationship between the cumulative percentage of population and the cumulative percentage of wealth. The more the curve deviates from the diagonal line (the line of absolute equality), the higher the degree of inequality.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Visualization of inequality. It provides more detail than the Gini coefficient. When analyzing user contributions or product sales, drawing a Lorenz curve allows you to see at a glance how strong the "head effect" is, thereby deciding whether to serve the head or the long tail.

Anchor fast decisions

A curve plotted with the cumulative percentage of population (from poorest to richest) on the horizontal axis and the cumulative percentage of income on the vertical axis. The more it deviates from the diagonal line of absolute equality, the more unequal the income distribution; it directly corresponds to the Gini coefficient.

Theil Index

The Theil Index, also known as the Theil Index, is a statistical measure of economic inequality. It has also been used to measure other social inequalities, such as racial segregation. The Theil Index is derived primarily from the concept of information entropy in information theory. The Theil Index equals information redundancy, that is, the maximum possible information entropy of the data minus the observed information entropy. It is a special case of the generalized entropy index and can be viewed as a measure of redundancy, diversity, inequality, non-randomness, and compressibility.

Gini Coefficient

The Gini coefficient (English: Gini coefficient) is an indicator for measuring the fairness of income distribution. It was defined by Italian scholar Corrado Gini in the early 20th century based on the Lorenz curve proposed by American economist Max Lorenz in 1905. This coefficient is a ratio between 0 and 1. The Gini index is the Gini coefficient multiplied by 100 as a percentage. In terms of people's income, the Gini coefficient has a maximum of "1" and a minimum of "0".
