Cost of living is the BEA regional price parity for all items, where 100 is the national average. Concentration is the BLS location quotient: how much more of the local workforce does this job than the national average, so 2.00× means twice the national share. It is often the reason wages differ — a place that concentrates an occupation has the employers and the competition for it. Metro areas where water and wastewater treatment plant and system operators wages are suppressed by BLS for confidentiality are omitted.
