We have a solid ratio of visitors, all things considered.
These ratios make sense.
If you check out the best selling console/Steam genres in the table someone posted in this thread about what percentage of players in each genre are female, these % are representative.
There is also a similar ratio between gamedev workers and it's above what Sony (previous gens), Nintendo (during WiiU and rearly Switch before Switch's AC and Pokemon), Xbox (previous gens) said they had and what someone researched a few years ago about Steam's website.
The 40-50% female players ratio we heard since many years ago came from mobile, because mobile gaming has a way higher userbase than console and PC and because the top mobile game genres match the ones that in the game genre preference by gender table appear as the ones with a higher percent of female players.
