Background

Overview

The informal economy is a critical aspect of India's economic structure, impacting employment, poverty, and policy effectiveness. Accurate measurement is vital for evidence-based policymaking and understanding the true state of the economy, especially given its large share in India.

The informal economy, also known as the unincorporated sector, comprises economic activities that are not regulated or protected by the state, often characterized by small-scale operations, self-employment, and lack of formal registration. Accurate measurement of this sector is crucial for comprehensive national income accounting, as it constitutes a significant portion of economic activity and employment in developing countries like India.

Impact on GDP

The informal economy's measurement significantly impacts overall GDP estimates, as highlighted by its role in recent nominal GDP revisions.

New Data Sources

Sectoral Variability

Revisions in the unincorporated sector's estimates are not uniform and vary across different sub-sectors (e.g., hotels and restaurants saw upward revision, trade saw downward).

International Recognition

International bodies like the World Bank have noted that reassessment of the informal economy was a main reason for India's recent nominal GDP revision.
