That's a good point about potential bias (those making more are more likely to respond). It's my intuition from living and working in this area for a long time that the responses are pretty representative. The surveyed group (UtahJS slack channel) I think skews more toward the less experienced (which shows in the years of experience chart), so if anything the data may be skewed that direction.

When I wasn't working remote, informally the ceiling seemed to me to be around $120k. That was a few years ago and these days I would have guessed more around $140k. Obviously I didn't have all the data points so good to see people who are at $175k-$200k.
