Limitations of Theil index
The Theil index is a commonly used measure to assess income inequality, but it does have some limitations. Firstly, it does not consider the distribution of incomes within each group being analyzed, meaning it may overlook disparities within specific segments of the population. Additionally, the Theil index assumes that all individuals within a particular group share the same characteristics and experiences, which may not reflect the reality of diverse societies. Another limitation is its sensitivity to changes in the size of population groups, making it difficult to compare inequality between different time periods or across regions with varying population sizes. These limitations should be taken into account when using the Theil index as a measure of income inequality.

Limitations of Lorenz curve
The Lorenz curve, while a useful tool for understanding income inequality, has its limitations. Firstly, it only focuses on income distribution and does not account for other socio-economic factors such as wealth, education, or access to public services. Additionally, the Lorenz curve assumes a homogenous population, disregarding variations within different segments of society. It also does not provide information on the causes or drivers of inequality, making it difficult to develop targeted policies for reducing inequality. Lastly, the curve can be misleading if the income distribution is highly skewed or if there are extreme outliers. These limitations highlight the need for complementary measures and a more holistic approach to understanding and addressing inequality.

Limitations of Gini coefficient
The Gini coefficient is a commonly used measure of inequality in economic and social contexts. However, it has several limitations worth noting. First and foremost, it fails to capture the full extent and dynamics of inequality within a population. It only offers a single value that does not reveal the distribution's shape or the specific groups experiencing unequal outcomes. Moreover, the Gini coefficient disregards non-monetary dimensions of inequality and fails to account for factors such as education, health, or social mobility. Furthermore, it assumes that any redistribution of income or wealth would be problematic, favoring increased inequality over equitable distribution. In summary, the Gini coefficient provides a limited perspective on inequality and should be supplemented with additional measurements for a comprehensive analysis.

Limitations of Atkinson index
The Atkinson index, a widely used measure of income inequality, has several limitations that need to be considered. First, it assumes that individuals have the same income preferences, disregarding the possibility of different needs or priorities. Second, it doesn't take into account other dimensions of inequality, such as wealth or access to opportunities. Additionally, the Atkinson index is sensitive to extreme values, making it less robust in situations where there are extreme income disparities. It also doesn't consider changes in income distribution over time, failing to capture the dynamics of inequality. Lastly, the Atkinson index does not account for non-monetary aspects of well-being, such as health or education, limiting its overall usefulness as a comprehensive inequality measure.
