If my memory serves right, SB, you're the one that suggests that costs of living have to be taken into account when determining whether one's wealthy or not (we'll stick with that instead of saying whether one's paid a lot or not, even though wealth = assets - liabilities).
So, yes, you're right, the last chart says that NJ teachers are the 6th highest when it comes to salary.
I'm reading the same charts, and the 1st chart says that NJ has the 5th most expensive housing (when compared to the average teacher salary of that state), and the 2nd chart says (I quote the site):
"in New Jersey a teacher makes $32,000 less that the median household income for that state."
which is the worst in the country (while in DC a teacher makes a little more than 10k more than the median household).
So it's you that have not taken into account the rest of the charts, because Caslon's statement is correct:
"According to the data on this website compared to average salary in the state
, NJ teachers make the least. "
And if 4 charts in one page is too much for you, in a separate pagehttp://www.teachersalaryinfo.com/cents-of-benefits-to-every-dollar-of-teacher-salary.html
NJ is solidly in the middle when it comes to teachers' benefits.
