ActionScript has died out in many places, but still has heavy use, drumroll in the Federal Goveernment sector. I was working in a shop recently with a guy who ONLY knew ActionScript/FLEX...... pathetic, but his salary sure wasn't.
Those incomes look like fairly typical mid-level individual salaries (in the DC area, at least). I would expect the household numbers to be higher than listed to account for those that have working spouses.
Yeah, those are definitely all possible. I would have preferred to use personal income but it's not available via the API, and I figured that using household income was better than nothing.
I could assert the following from the data:
* ActionScript developers are horribly underpaid, but more likely to marry lawyers, doctors and bankers.
* Haskell developers are relatively well paid, but more likely to live alone or with a stay-at-home parent.
* Pythonists get roughly the same salary as Haskell developers, but their partners are all low-paid key workers.
