The Central Statistical Organization (CSO), now part of the National Statistical Office (NSO), is responsible for compiling and estimating the National Income of India. It does this by calculating key economic indicators like Gross Domestic Product (GDP), Gross National Product (GNP), and Net National Product (NNP). The CSO employs a range of data, including output from various sectors like agriculture, manufacturing, and services, to estimate the country's overall income. The organization plays a crucial role in providing statistical data that is used by policymakers to shape economic and fiscal policies. National income estimates are essential for understanding the state of the economy, growth rates, and living standards. The CSO's data is critical for measuring economic performance and for international comparisons of economic activity.
