Case study design and methodology
Case study design and methodology involves a detailed examination of a specific subject or event. It aims to gather in-depth information and provide rich insights into real-life scenarios. This research approach allows researchers to explore complex phenomena and understand the context in which they occur. The design typically involves collecting various types of data, such as interviews, documents, and observations. It emphasizes the holistic and comprehensive analysis of the case, capturing both the breadth and depth of the subject. Researchers must carefully plan and execute the case study to ensure validity and reliability. By employing an appropriate methodology, this research method can offer valuable contributions to various fields and disciplines.

Methodology
Methodology refers to the systematic approach followed in conducting research or the overall approach taken to solve a problem. It involves various steps such as data collection, analysis, and interpretation to achieve the desired objective. A well-defined methodology ensures that the research is conducted efficiently and the results obtained are reliable and valid. It provides a clear roadmap for researchers to gather relevant information and draw meaningful conclusions. By adhering to a well-structured methodology, researchers can minimize bias and enhance the overall quality of their work. Ultimately, a strong methodology serves as the foundation for any successful research or problem-solving endeavor.

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.
