Hi Matthew. I found a survey that was conducted a few years ago in California by the National Center for State Courts. Here's a sample of what they list for judge compensation for state courts (I'm rounding the numbers a little bit): Associate Justice $218,000; Court of Appeal: $205,000; Superior Court $179,000.
Don't forget that there are all kinds of judges, and all kinds of courts. Some of these positions are appointed, and some are elected by the voting public.
