By drawing from 4 types of data collected ad hoc within each MINDtheGEPs' implementing partners this report assumes a pivotal role in enriching our comprehension of gender equality within diverse contexts. It was first shared as a deliverable from the project titled D2.2 Report on gender imbalances at meso-level. After anonymization of results, in order to facilitate reading this report has been divided into three sub-reports: Gender Imbalances at the Meso-Level: A Multi-Indicator Approach to Organisational Gender Data, Gender Imbalances at the Meso-Level: Gathering Insights from Researchers Through a Web Survey, and Gender Imbalances at the Meso-Level: Gathering Insights Through Interviews with Key Informants and Researchers. In this report, Gender Imbalances at the Meso-Level: A Multi-Indicator Approach to Organisational Gender Data, through 53 indicators, such as the share of women in governing bodies or in different grades, the share of women applying for or winning competitive funds, and the existence of gender measures, we offer a straightforward quantitative portrayal of the gender gaps in each implementing organisation.
