Relative pay is the role's annual median divided by the BLS all-occupations (SOC 00-0000) annual median for Chicago-Naperville-Elgin, IL-IN. Location quotient compares this occupation's share of local jobs with its national share. It measures concentration, not pay.
What these figures leave out for technology hires
BLS OEWS wages are straight-time gross pay. They include base rate, guaranteed pay, incentive pay including commissions and production bonuses, and cost-of-living allowances. They exclude overtime, shift differentials, nonproduction bonuses, severance and employer-paid benefits.
Our interpretation, not a BLS statement: the BLS definition does not name stock or equity grants, so we treat them as outside these figures and add nothing for them. If a technology offer leans on discretionary bonus or equity, we read the published figure as describing only the cash pay inside the BLS definition.
