Evolution of Regional, Age and Gender Demographics in the ATLAS Collaboration

The ATLAS Collaboration consists of more than 5000 members, from over 100 different countries. Regional, age and gender demographics of the collaboration are presented, including the time evolution over the lifetime of the experiment. In particular, the relative fraction of women is discussed, including their share of contributions, recognition and positions of responsibility, including showing how these depend on other demographic measures. https://indico.desy.de/event/34916/contributions/147185/
