The members of the GBD Injury expert group were volunteers and did not derive any salary support from the GBD project. However, several members had ongoing research projects in closely associated areas, allowing them to contribute more substantially.

This project relied primarily on secondary analysis of existing data sources. These data sources have involved many years of hard work on the part of researchers, professionals, medical institutions and national and international health and transport agencies. Without the primary data collection undertaken by these national and international agencies, the analytical work of the expert group would not have been possible.
