NSO Uses Model-Based Method For Uttar Pradesh Data Gaps
The NSO conducts large-scale household surveys across diverse socio-economic themes to generate reliable statistical inputs for policymaking. Among these, the HCES plays a vital role by capturing data on household consumption patterns, living standards, and demographic characteristics at national and state levels.
Aim of the Study
The study was undertaken following the National Statistical Commission’s Steering Committee recommendation to pilot model-based estimation techniques for generating district-level insights. A dedicated committee chaired by Dr Mausumi Bose, Former Professor at the Indian Statistical Institute (ISI), Kolkata, was constituted to explore the feasibility of estimating Monthly Per Capita Consumption Expenditure (MPCE) for each district in Uttar Pradesh using HCES data.
The project received technical support from the NSO and the Directorate of Economics and Statistics (DES), Government of Uttar Pradesh.
While HCES data provides robust estimates at national and state levels, it often lacks district-level precision due to limited survey samples. To address this gap, the study adopted a model-based approach, testing whether statistical modelling could generate accurate, cost-effective estimates for smaller administrative units.
Methodology
The research employed a statistical technique called Small Area Estimation (SAE), which enhances data accuracy for smaller regions by combining survey data with auxiliary administrative information. This approach “borrows strength” from related datasets, improving the stability of estimates where direct sampling is insufficient.
The study utilised two types of statistical models — Fay–Herriot (FH) and Spatial Fay–Herriot (SFH) — and incorporated auxiliary data such as:
Number of old-age pension beneficiaries
Number of Ayushman Bharat (PM-JAY) patients
Number of domestic LPG connections
Number of Antyodaya food scheme beneficiaries
Key Findings
The top five rural districts with the highest average MPCE were:
Bagpat
Saharanpur
Gautam Buddha Nagar
Meerut
Ghaziabad
In urban areas, the leading districts were:
Gautam Buddha Nagar
Gonda
Ghaziabad
Bagpat
Lucknow
The study showed that model-based estimation can be a cost-effective and scalable solution for generating district-level statistics using state-level survey data.
Conclusion
The findings reaffirm the potential of statistical modelling as a reliable tool for filling data gaps and improving local-level governance. By providing district-specific insights, the method enables policymakers to design targeted welfare programmes, monitor living standards, and reduce regional inequalities.
The success of this pilot in Uttar Pradesh sets a precedent for extending the model-based approach to other states and socio-economic indicators, such as employment, health, and poverty, advancing India’s commitment to data-driven policymaking and sustainable development.
