Definition and concepts

The Red List Index is a multi-purpose indicator which measures the aggregate change in extinction risk across groups of species. It is based on the number of species in each category of extinction risk on The IUCN Red List of Threatened Species. This indicator is expressed as an index ranging from 0 to 1.
