What this pays, and what it is worth
- Illinois is one of the better-paying states for this job. The middle earner takes $123,500, which ranks 6 of 50 states with published figures. That is about 32.04% above the national middle.
- This is one of the better-paid jobs in Illinois. It ranks 36 out of 494 occupations the state publishes figures for, which puts it in the top quarter locally.
- Prices here sit close to the national average, so the adjustment changes little. From $123,500 the take-home is $89,710, which is worth about $90,749 in comparable money. Tax does most of the work here, not cost of living. The average is lower, $115,980, so pay clusters nearer the top than usual.
- Illinois ranks 6 of 50 states publishing a median for first-line supervisors of firefighting and prevention workers, at $123,500 — about 32.04% above the national median. A state's position on nominal pay is the figure wage tables report and the least informative of the three on this page, because it survives neither the tax adjustment nor the price adjustment intact for most occupations.
- Within Illinois, first-line supervisors of firefighting and prevention workers ranks 36 of 494 occupations by median pay, placing it in the top quartile of the local distribution. This is the comparison a resident actually makes — against neighbors rather than against the same job elsewhere.
- Illinois's price level is near the national average, so price deflation is close to neutral for first-line supervisors of firefighting and prevention workers on its $123,500 median: $89,710 retained after tax becomes $90,749 in national-average terms. Where the price adjustment is small, the tax stack is the dominant determinant of the real outcome. The mean of $115,980 falls below the median, a left skew that is uncommon in wage data.

Sources and assumptions
- Treat $123,500 as a midpoint for Illinois, not a promise. The tenth percentile is $73,690 and the ninetieth is $153,820 — a wide band, and where you land in it depends on far more than the state.
- One filer, no dependants, no pension contributions — that is the household behind Illinois's $89,710, worked from $123,500. That is on purpose. It lets states be compared with each other, not with each other's family circumstances. Local city taxes are left out. Locally this work ranks 36 of 494.
- Two cautions on $90,749, the adjusted value of that $123,500 median. It levels out prices with a single number for all of Illinois. No actual address matches that. The wage figures and price figures are also from different years. Each is published on its own timetable. This work sits at 36 of 494 locally.
- The Illinois median of $123,500 describes the midpoint of a distribution spanning $73,690 to $153,820. Because that spread is typically larger than the interstate spread, a state median is a weak predictor for any individual worker in this occupation.
- The Illinois take-home of $89,710, on $123,500 for work ranking 36 of 494 locally, models the simplest household deliberately: holding it constant is what makes the interstate comparison meaningful. It also means the absolute figure overstates liability for most real filers, and municipal income taxes are outside the model entirely. The occupation ranks 36 of 494 in the state.
- This $90,749 adjusted figure, worked from $123,500, rests on a state-level price parity averaging over within-state dispersion larger than much of the between-state dispersion. Wage and price vintages differ by publication schedule. The result is directionally sound and not address-specific, for work at 36 of 494 in the state. The occupation ranks 36 of 494 locally.
Questions people ask
Is this the average pay for the job?
No — it is the middle. Half of these workers earn more and half earn less. The average is $115,980, pulled upward by the top of the range, which is why the middle is the fairer number to plan against.
How much does pay for this job actually vary?
The range here is narrow. From $73,690 at the bottom tenth to $153,820 at the top, pay for this work clusters rather than spreads.
What does this pay actually buy where I live?
Further than the number implies. Illinois is cheaper than the national average, so this take-home behaves like $90,749 in national terms.
Where does the difference between the wage and my paycheck go?
Into four separate taxes, not one. Federal income tax, Social Security and Medicare apply everywhere, and Illinois adds its own income tax on top — which is why $89,710 of this wage survives to your account.
Why is this job missing from some states?
The survey withholds small samples rather than publish an unreliable number. Pay appears for 50 states here, and a missing state means too few reports, not no jobs.
How does the published median differ from the mean for this occupation?
The median is the midpoint of the distribution; the mean for this occupation in Illinois is $115,980. Wage distributions are right-skewed, so the mean exceeds the median wherever a minority earn substantially more. BLS publishes both because substituting one for the other misstates a typical worker's pay.
What is the dispersion of this occupation's wage distribution?
The tenth-to-ninetieth percentile span ($73,690 to $153,820) sits at or below the family's median dispersion, indicating relatively standardized compensation. Percentiles are published per state, so this dispersion is specific to Illinois rather than a national figure.
What is this occupation's price-adjusted compensation in this state?
Illinois's regional price parity is at or below the national average, so nominal wages understate purchasing power. Take-home deflated by the state price level is $90,749 in national-average terms. The adjustment uses an all-items index and does not isolate housing.
What accounts for the gap between gross wage and take-home here?
Take-home of $89,710 reflects federal income tax, OASDI, Medicare and Illinois income tax for a single filer with no adjustments. The state layer is levied in addition to the federal one; only its rate and base differ between states.
Why does this occupation lack published estimates in every state?
BLS suppresses estimates failing disclosure or reliability criteria. This occupation has published state-level estimates in 50 of the fifty-one jurisdictions. Suppression reflects sample size and confidentiality rules, and cannot be read as an absence of employment.
