I do wonder if the 13% female participation rate is specific to just one or a limited number of projects, if it's an average across all projects, or if there is significant variation between projects.
Hi Anne, the 13% is based on the reported 12.94% based on a survey [1] -- though it, as most surveys, is subject to self-selection bias. It had a massive number of respondents (N=175,000), but still required people already on the WP sites to choose to participate. There was also an earlier survey (N=151) that put it at 7.3% [2]. Neither had a project break-down.
