A core objective of the GEDII project is to provide empirical evidence on the potential link between gender diversity within teams and research performance/innovation. Towards this goal, the present report describes the methodological foundations of the Gender Diversity Index which is a composite indicator that is applicable at team level and provides a summary measure of the outcome of gendered processes. A composite indicator is obtained when individual indicators are compiled in a single measure on the basis of a multi-dimensional concept. For the Gender Diversity Index, this means aggregating several team level gender diversity measures into a coherent conceptual and statistical whole. This methodological report describes the steps adopted in the construction of the Gender Diversity Index. First, a brief overview of the team survey is provided. This is followed by an account of what metrics were used and by the results of the multivariate analysis. Next, the aggregation steps are examined and an assessment of the robustness of the Gender Diversity Index. The Gender Diversity Index is then described and exemplified in detail through some team cases, before some concluding remarks are provided.
