## Income Equality Measurement

This calculator is prepared by assuming that the level of income distribution is calculated using the **Harmony in Gradation. **

Here is the correlation coefficient between the index and the level of income distribution of the population

a. Index = 1: The level of income distribution of the population is perfect

b. Index = 0.75 s / d 0.99: The level of income distribution of the population is good

c.Index = 0.5 to 0.75: The level of income distribution of the population is moderate

d. Index 0.5: The level of income distribution is bad

Procedure: (1). Fill in N = number of income grouping groupings, in this case, the population income groupings may be made into 3, 4, 5 or more. Suppose the population is divided into 3 groups, meaning the population is grouped into rich, medium and poor groups. Note that in each group there should be the same number of people, for example, will be divided into four income groups, means that in each group there are 25% of the population; (2). Fill in the total income of each group; (3). Enter **Calculate**

Population Income of Group 1 : |

#### Calculation Result:

Number of Population Income (N): | |

Index of the Perfect Income Equality: |
