Analyzing the average income in India based on Income Tax Return (ITR) data can provide valuable insights. Here are some points to consider:

• ITR Data: Income tax returns filed by individuals can provide information about their income, deductions, and tax liabilities. Analyzing this data can help estimate average income levels.
• Time Period: The average income in India has been observed over the last nine years, indicating a long-term trend. This allows for a more comprehensive analysis of income growth.
• Comparison: The Prime Minister stated that the average income has increased from ₹4 lakh to ₹13 lakh over this period. Comparing ITR data from different years can confirm or challenge this assertion.
• Sampling Bias: It's important to note that ITR data captures only a subset of the population, primarily those who fall under the taxable income bracket. This may not represent the entire population's income distribution accurately.
• Regional Disparities: Analyzing ITR data can also shed light on income disparities across different regions or states in India, providing a deeper understanding of the overall average income.

While analyzing average income based on ITR data provides valuable insights, it is important to consider its limitations and supplement it with other sources of information for a comprehensive understanding of India's income trends.
