Openings a year counts new jobs plus the ones that open when people retire or move on — a truer picture of your odds than growth alone.

“Median” means half earn more and half earn less. Your city, employer, and years on the job move it a lot — that is what the 10th-to-90th range shows.

What it pays in your state

Statewide medians are a better starting point than the national number. Your city and experience still matter.

The honest take

Well-paid investigative work, but it is rarely entry-level and usually comes after years on patrol.
