The Bureau of Labor Statistics provides information about income distribution of different jobs. The latest data that was available for download is from May 2017. I put together a graph to understand who jobs lie where. In the graph, the horizontal axis is job density, which is the number of people who have this job for every 1,000 workers in the US - so further to the right means more people do this job. The vertical axis is the average hourly income for people in that job. The red line at $24 is the average across all jobs in the US. I overlaid the hexagons as a way to see the density of the dots - which part of the graph has the most dots.
