For a while back there, I had more than 54,000 followers on Twitter, for what that’s worth. Current number after some losses over the last couple of years through general attrition, spam and bot clearouts etc, now means my follower count is down to about 43,000 followers. I did an analysis of declared pronouns, bio details and name on a sample of 2,000 of the most recently active based on 200 tweets in my timeline (using a freely available tool called proporti.onl)
The breakdown of followers is as follows: 32% male, 16% female, 52% not known.
The proportions are different for the people I myself follow. I don’t tend to keep following people who don’t follow me and I limit the total number to 2000, at the moment it’s just under 1800 that I follow.
