NJ Government Employee Data
I've just discovered two excellent sources of information on NJ government employees.
The first source is the NJ State Government Workforce Profile, which is updated annually. This report includes extensive data on headcounts, salaries, educational levels, job categories, union representation, etc. I'm still working my way through the 2006 report, which is 70 pages long.
The second source is the NJ Department of Labor wage survey of public and private employees, which is also updated regularly. Most teachers fall under industry code 61. Most other government employees can be found under industry code 92.
Although both sources provide wage and salary data, neither seems to include benefit costs, such as medical care or retirement benefits. Given the magnitude of these liabilities, that's a real shortcoming. However, there's still a lot of good information in these reports.
