(Backing this up... though as I write this, the site with the source data is down - https://flag.dol.gov/programs/prevailingwages ... so using one that uses that data... https://flcprevailingwage.com )

Software Developer (15-1252). Eau Claire County. Bachelors degree. 0 experience.

The prevailing wage is Level 1 Wage:$36.54 / Hour - $76,003 / Year

Change it to San Francisco County.

Level 1 Wage:$65.24 / Hour - $135,699 / Year

And so, as noted... it is location dependent.
