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 1.12 means plumbing, heating & ac contractors are 12% over-represented in South Dakota's business mix relative to the U.S. average.
