California -> Austin
I think you could probably chalk a lot of this up to where company leadership has their vacation homes.
1. No state income tax.
2. Comparatively cheaper home prices, though with news link this perhaps not for long, centrally located Austin single family homes are incredibly expensive now.
3. Vibrant tech and VC community - not at the same level as SV but a not-too-distant second-or-third.
This Bloomberg article had a chart showing change in adjusted gross income from 2017 to 2018, but I'd be interested in something going back a few decades.

Uh, no.
Austin has a lousy VC community. There are countless articles about it.
And, as for tech, for software it's mainly only Tivoli alums--and a lot of the best ones decamped for greener (read: better salary not in Austin) pastures. IBM as a technical presence has been gone forever (the Advanced Workstation Division was quite amazing and IBM Somerset was one of the PowerPC development arenas). Apple just came in so hasn't spun anybody out yet.
