Evaluate the significance of improved measurement of the unincorporated sector in India's national accounts. What data challenges persist in capturing the informal economy?

The unincorporated sector — non-agricultural enterprises outside the corporate fold — contributes significantly to India's GDP and acts as a backbone for the incorporated sector by supplying goods and services [4]. Its improved capture in the new GDP series with base year 2022-23, released by MoSPI on 27 February 2026 [1], is a genuine but partial statistical advance.

Significance of improved measurement

• Accuracy of the level and composition of GDP: the new series draws on fresh enterprise data, notably ASUSE, alongside PLFS, while refining estimation for the tertiary and secondary sectors [3]. This replaces older indicator-based extrapolation with directly surveyed activity.
• Scale of the evidence base: ASUSE is India's largest annual enterprise survey, covering manufacturing, trade and other services across rural and urban India, with close to five lakh establishments surveyed in 2023-24 [4] — a frame wide enough to anchor national accounts.
• Policy relevance: since nominal GDP is the denominator for fiscal deficit, debt and tax-to-GDP ratios, a more accurate level improves the credibility of fiscal targeting [2].
• Institutional discipline: rebasing on a post-COVID "normal" year with robust cross-sectoral data [1], rather than on an ad hoc trigger, strengthens MoSPI's methodological transparency, reinforced by a published FAQ set [3].

Persisting data challenges

• Coverage gaps: ASUSE is confined to the non-agricultural unincorporated sector [4], leaving informal agricultural and allied activity outside its frame.
• Frame obsolescence: informal units are born, migrate and shut down rapidly, so sampling frames age faster than survey cycles.
• Comparability breaks: PLFS itself was revamped in 2025 — a new sampling design and a shift from a July-June to January-December cycle [5] — complicating consistent time-series inputs.
• Transition friction: back-series data under the new base is expected only by December 2026 [3], limiting analysts' ability to compare across series meanwhile.

Overall, the reform substantially improves measurement of the visible informal economy while leaving its statistical frontier — agriculture-linked and micro-scale activity — inadequately mapped. Sustained investment in frame updation, synchronised survey cycles and early release of a reconciled back series would convert a better base year into genuinely better national accounts.
