How these figures are calculated
The pay percentile above is computed live from PlainGovJobs' own OPM FedScope database, not hand-typed: National Mediation Board's average salary is ranked against every other federal agency's average salary, agency-by-agency (not weighted by headcount), and the percentile is the share of agencies whose average is strictly lower.
The sub-agency pay-span bars sum each sub-agency's own employee_count into one of five salary bands based on that sub-agency's average salary; the bands add up exactly to National Mediation Board's total employee count, since every sub-agency is counted in exactly one band.
