Estimating the national income of a country is necessary because it indicates the overall performance of the economy. National income gives an idea about the total value of goods and services produced in a country within a specific period. By estimating the national income, we can analyze the growth and development of the economy, which helps in making economic policies and strategies. It also helps in assessing the standard of living of the people in the country. Additionally, it provides crucial information for investors, policymakers, and governments, as it assists them in identifying profitable ventures, making economic decisions, and conserving national resources. Finally, equitable distribution of wealth is also possible through proper estimation of national income as it enables the government to plan and execute social welfare programs for the benefit of the underprivileged.
