At the conclusion of all IAU-sponsored meeting, the symposium chairs must complete an online form which capture gender statistics associated with the meeting as part of their post-meeting reporting duties. Both historical and current data is added to this site periodically as new data arrives.
Here we present the gender statistics of the participants and organising committees of IAU meetings, with the total number of people in each category numerated and the percentage of women in parentheses.
