Reading this
An establishment is a single physical location where business is conducted. A firm with multiple locations counts as multiple establishments. "Avg pay" is wages and salaries per employee, including bonuses and tips — for proprietorships, the owner's take is largely outside this number. The location quotient (LQ) of 1.06 means plumbing, heating & ac contractors are 6% over-represented in New Jersey's business mix relative to the U.S. average.
