The pattern I noticed was that my behavior of eating alone in public as a woman was, in fact, unusual as other people seemed to think. I haven't noticed enough other women eating alone to notice any patterns concerning characteristics of women who eat alone. It really seems rather rare and my interest in the phenomenon was limited in scope to wondering why it got such weird reactions from other people and paying enough attention to verify that, yea, verily, it's genuinely unusual. People aren't merely making that part up.

I didn't pay attention beyond that. It's not some formal study with records, etc.
