Definitions and calculation of Atkinson index
The Atkinson index is a measure of income inequality within a population. It is calculated by taking the reciprocal of the elasticity of a society's welfare function with respect to income. This index ranges from zero to one, with higher values indicating greater inequality. To compute the Atkinson index, one needs individual household income data, which is then adjusted for economies of scale and regional price differences. The calculation involves comparing each household's income to a hypothetical equal-income distribution. This index provides insight into the extent of wealth concentration and can be used to assess the effectiveness of redistributive policies in reducing inequality.

Calculation method of Atkinson Index
The Atkinson Index is a calculation method used to measure income inequality within a given population. It was developed by economist Anthony Atkinson in 1970 and is widely used as a way to understand the distribution of wealth. The formula for calculating the Atkinson Index involves taking the sum of the absolute differences between each individual's income and the average income, and then dividing that by the average income raised to the power of the Atkinson coefficient. The Atkinson coefficient determines the level of aversion to income inequality within the index, with a higher coefficient indicating a greater aversion. Overall, the Atkinson Index provides a valuable tool for analyzing and addressing income inequality in society.

Calculation method of Theil index
The Theil index is a calculation method used to measure income inequality within a population. It provides a numerical value that represents the disparity between different income groups. To compute the index, data on the distribution of income is needed. The index takes into account both the number of individuals in each income group and the income share within these groups. By doing so, it captures the extent to which income is unequally distributed in a society. The Theil index has been widely used in economic research and policy-making to assess income disparities and inform decision-making processes aimed at reducing inequality.

Definition and Calculation of Gini Coefficient
The Gini coefficient is a measure of income inequality within a population. It ranges from 0 to 1, with 0 indicating perfect equality and 1 indicating extreme inequality. To calculate it, one must first sort the population by income level. Then, a Lorenz curve is constructed, which plots the cumulative percentage of income against the cumulative percentage of the population. The Gini coefficient is obtained by dividing the area between the Lorenz curve and the line of perfect equality by the total area below the line. A lower Gini coefficient suggests a more equal distribution of income, while a higher coefficient indicates greater inequality.

Calculation of the Theil index
The Theil index is a measure used to assess inequality within a given population. It takes into account both the distribution of income and the number of individuals in each income group. The calculation involves taking the logarithm of each individual's income, summing them, and then dividing by the total population. This creates a value that represents the average inequality across all income groups. A higher Theil index indicates a greater level of inequality, while a lower index suggests a more equal distribution of income. By understanding and analyzing the Theil index, policymakers and researchers can gain insights into the economic disparities within a society and develop strategies to address them.

Calculation formula for Theil index
The calculation formula for Theil index measures inequality within a population or group. It provides a numerical value that represents the level of disparity in income or distribution of resources. To compute the Theil index, one needs data on individual incomes or resource allocations. The formula involves summation and logarithmic functions to capture the variation in the distribution. Theil index values range from 0 to 1, with 0 indicating perfect equality and 1 representing extreme inequality. This index is a valuable tool for policymakers, economists, and sociologists, as it helps assess and address socio-economic disparities and design targeted interventions for a more equitable society.

Calculation methodology of Gini coefficient
The Gini coefficient measures income inequality within a population. It is calculated using a formula that compares the cumulative income shares to the cumulative population shares. To calculate it, first arrange the population in ascending order by income. Then, calculate the cumulative population percentage and cumulative income percentage at each income level. Next, subtract the cumulative population percentage from the cumulative income percentage to get the Gini coefficient values at each income level. Finally, sum up the Gini coefficient values and divide by the total number of income levels. A Gini coefficient close to 0 represents perfect equality, while a coefficient close to 1 indicates extreme inequality. The calculation method provides valuable insights into the income distribution within a society.

Calculation of Theil index
The Calculation of Theil Index is a statistical measure used to quantify inequality within a given population or dataset. Developed by econometrician Henri Theil, it provides a comprehensive analysis of inequality by taking into account both within-group and between-group disparities. The Theil Index is calculated by considering the logarithmic differences between individual values and the overall average. The resulting index ranges from 0 to 1, with higher values indicating greater inequality. This method allows policymakers and researchers to evaluate the distribution of income, wealth, or any other relevant variable, making it a valuable tool for understanding and addressing societal disparities.
