Analytics are often used for demographic purposes, but they aren’t for that: https://en.m.wikipedia.org/wiki/Analytics

Ranking comments by quality is absolutely tangential to analytics. It’s processing feedback, and rearranging the pangs in orders to make it more pleasant to readers… it’s real close to a-b testing.

If I can see the number of votes and replies and their affect on my account (karma count), those are analytics of my comments and stories.

Demography is the genre of analytic.
