BLS draws metro boundaries from the OMB MSA definitions, so Durham-Chapel Hill, NC covers the central city plus outlying counties tied to the metro economically.

Before using this metro median as a negotiation anchor, triangulate against the same occupation's national profile (linked below), its state-wide NC data, and peer-metro comparisons — a median is a starting point, not a ceiling.
