This briefing provides an overview of the 2025 Index of Multiple Deprivation (IMD) for Norfolk. It is intended to inform stakeholders about the latest data on deprivation, highlight key findings for Norfolk and its districts, and explain how changes in methodology affect interpretation.
Deprivation influences health outcomes and access to services. The IMD ranks every area in England by relative deprivation using 55 indicators across 7 domains (income, employment, education, health, crime, housing barriers, living environment).
The IMD was recently updated in November 2025, introducing a new calculation method with additional indicators and revised domains. As a result, changes compared to 2019 should be interpreted with caution, as differences may reflect methodological updates rather than real-world changes.
