They differ by state. Or were you looking for any state? I know there's some kind of national website of statistics but I can't find it and I don't recall if it had rates.
ETA: NJ's are pretty high, but we are (as a state) one of (if not THEE) highest cost of living areas in the US... so it doesn't go as far as it would elsewhere.
