Centre rolls out uniform DDP guideline with 2022-23 base year for 26 states
Synopsis
Key Takeaways
The National Statistics Office (NSO) on Wednesday, 3 June released a uniform guideline for the compilation of District Domestic Product (DDP) estimates with 2022-23 as the new base year, aiming to standardise sub-state economic measurement across India. The framework, issued by the Ministry of Statistics and Programme Implementation (MoSPI), is designed to ensure consistency and comparability of district-level estimates across all States and Union Territories.
What the guideline covers
The document lays out the concepts, coverage, data sources, estimation procedures and methodologies for computing Gross District Domestic Product (GDDP), Net District Domestic Product (NDDP) and Per Capita Income at the district level. It is the first comprehensive sub-state framework tied to the revised 2022-23 base year series.
Bottom-up approach at the core
The guideline primarily emphasises a bottom-up approach for DDP compilation, wherever district-level data is feasible to collect. In sectors where granular district information is not adequately available, MoSPI has recommended top-down methods with suitable allocation indicators to derive consistent estimates.
Where states stand today
At present, 26 States and Union Territories are compiling DDP estimates. MoSPI said it is making continuous efforts to onboard the remaining States and UTs so that district-level estimates are produced in a uniform and comparable manner nationwide.
Why it matters
Reliable and comparable DDP estimates are expected to support decentralised planning, evidence-based policy formulation and regional development analysis at the district level, the official statement said. The guideline is also expected to help States and UTs improve their data systems and strengthen statistical capacity for robust sub-state estimates.
How the document was finalised
MoSPI had uploaded the draft guideline on its official website on 7 April 2026 for consultation with stakeholders, including States and UTs, academic institutions, researchers and other users of sub-state statistics. The finalised version, released this week, follows a detailed examination of comments and suggestions received during that consultation.
Going forward, harmonised DDP data is likely to feed into Finance Commission deliberations, district aspirational planning and targeted central scheme allocations.
