PyLadies History of Growth

PyLadies communities has opened more chapters than other community in that space, and they are most broadly represented in the world. There are also many chapters which are non-active.

Some chapters were dissolved, or rolled into other communities such as: Django Girls, Girl Develop It, general Python meetup groups, PyData meetup groups.


A number of meetup groups closed this year. For that reason, members in those chapters are no longer counted as PyLadies members.
