Funded by the International Council for Science (ICSU) and supported by many international scientific bodies including the IMU, the Gender Gap in Science Project is collecting data to develop a broader picture of the status of mathematicians and scientists across the world. The results will provide data about the situation of scientists and mathematicians worldwide, as well as focused information about women in these fields. The data will help inform interventions by ICSU and member unions to increase participation, especially for women. More information about the project is available
The survey is open until October 31st 2018 and can be accessed
