A quantitative tool developed by ACAPS for measuring and comparing the severity of humanitarian crises. It enables evidence-based prioritisation by integrating data from over 30 credible publicly available sources into a single, transparent composite score.
The INFORM Severity Index evaluates the scale and severity of humanitarian need at both national and subnational levels. By combining dynamic crisis impact data with structural indicators, it produces severity scores that are comparable across crises, countries, and time periods.
The index explicitly acknowledges that not all people affected by a crisis experience the same level of need — and aims to capture this distribution of severity through its multi-dimensional approach.
All indicators are scored on a 0–10 scale. Each dimension is a weighted composite of sub-indicators capturing specific aspects of crisis severity. The final index score is derived by aggregating across all three dimensions.
Final scores are grouped into five categories:
A crisis qualifies for inclusion in the index if at least one of the following conditions is met:
Activation also takes into account national response capacity and the extent to which external humanitarian intervention is required.
Each crisis score is accompanied by a reliability estimate reflecting the quality, recency, and coverage of the underlying data. Where fewer or lower-quality sources are available, the reliability rating is lower, signalling increased uncertainty in the score.
