# The Gini index
**The Gini index** is like a score that shows how **equally or unequally** money is distributed among people or households in a country.
# Calculate
- Imagine a line representing **perfect equality**, where everyone has the same amount of money.
- Then you compare that line to the actual distribution of money using something called a **Lorenz curve**.
- The **Gini index** measures the difference between the two lines.
- A **Gini index of 0** means **perfect equality**, where everyone has the same amount of money.
- A **Gini index of 100** means **perfect inequality**, where one person has all the money and everyone else has none.
**The Gini index** is important because it helps us understand how **fair or unfair** a country's economy is.
A **lower Gini index** indicates a **fairer distribution of wealth**, while a **higher index** indicates **more inequality**.
**The Gini index** is a way to see how fairly money is distributed among people in a country.
A **lower value** means **more fairness**, while a **higher value** means **more inequality**.
