Statistics Day 2026 Theme

Theme: “Unlocking the Potential of Administrative Data”

The theme emphasises the increasing importance of administrative data, which is generated during the routine functioning of government departments.

Examples include:

• GST records
• Income Tax data
• Aadhaar-enabled databases

The objective is to improve:

• Data quality

Why Administrative Data Matters

Administrative data is emerging as a key pillar of modern governance because it enables governments to generate reliable statistics without relying solely on expensive surveys.

Benefits

As India’s digital ecosystem expands through platforms like Aadhaar, GSTN, Digital Health Mission, and e-Governance initiatives, administrative datasets are becoming increasingly valuable for official statistics.
