My mom had my hair analyzed once when she was in cosmotology school and they told her my hair is fine. You might ask your barber/stylist next time you go for a cut what they think. my hair is dense but when you look at the fine strands individual they're barely visible. I think that's why a lot of people perceive high density as coarse.
