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 computer and information research scientists wages are suppressed by BLS for confidentiality are omitted.
