There is something really off about these numbers. unless i'm totally off about how many entry level employees are in the area vs mid/senior level employees. Since this data is collected by people reporting their salaries, I think that people that are more junior are more likely using and submitting their salary info to the site. This will skew salary data toward entry level employees.

I also see Glassdoor is accounting for stocks now, though that's not factored into avg salary, but total comp. Looking at some companies this raise compensation by ~$50k.
