What this pays, and what it is worth
- Neither high nor low. Illinois is 20 of 48 states for this job, with a middle wage of $124,180. What that is worth is the question the rest of this page answers.
- Locally, this pays well. Among 494 occupations Illinois reports, this job comes in at 35 — comfortably in the upper quarter.
- No great distortion either way. Illinois costs about what the country costs, so from $124,180, take-home of $90,141 is worth roughly $91,185 in national money. The average comes to $127,000, above the middle, thanks to the top of the range.
- Illinois ranks 20 of 48 for information security analysts at $124,180. The nominal figure is unremarkable; the adjusted figures are where the state's actual position for this occupation is determined.
- Information security analysts ranks 35 of 494 occupations by median in Illinois, in the top quartile. Within-state position is largely independent of national position, so this holds regardless of how the state compares to others for the same work.
- Price parity in Illinois is near the national base, so for information security analysts, whose median is $124,180, the adjusted figure of $91,185 differs little from $90,141 retained after tax. The state's position for this occupation is therefore set by wage and tax rather than by living costs. At $127,000 the mean overshoots the median — the usual right-skewed shape.

Sources and assumptions
- Treat $124,180 as a midpoint for Illinois, not a promise. The tenth percentile is $78,760 and the ninetieth is $172,830 — a wide band, and where you land in it depends on far more than the state.
- That $90,141 take-home in Illinois comes from $124,180. It is the no-frills case: single filer, standard deduction, nothing set aside before tax. Real circumstances almost always reduce the tax. City and school-district taxes are not counted at all. Locally the work ranks 35 of 494.
- The wage data and the price data come from different years. That is how each is published. The price adjustment behind $91,185 uses one figure for the whole of Illinois. A city and a rural county there can differ by more than two states do. Out of 494 occupations the state publishes, this one sits at 35.
- The Illinois median of $124,180 describes the midpoint of a distribution spanning $78,760 to $172,830. Because that spread is typically larger than the interstate spread, a state median is a weak predictor for any individual worker in this occupation.
- Retained pay of $90,141, from $124,180, assumes a single Illinois filer with the standard deduction and no elective deferrals. Pre-tax retirement or HSA contributions, dependants and itemized deductions all reduce it further; local income taxes, excluded here, would increase it in the states that levy them. This occupation ranks 35 of 494 locally, and the state ranks 20 of 48 for it.
- Wage and price series carry different reference periods, each published on its own schedule. The real-terms figure of $91,185, worked from $124,180, deflates by a statewide parity that conceals substantial intra-state variation, concentrated in housing — so it supports comparison between states rather than the pricing of a move to a particular Illinois address, on work sitting at 35 of 494 locally.
Questions people ask
Why is the pay range for this job so wide?
The label is broader than the work. From $78,760 at the bottom tenth to $172,830 at the top, the same title covers roles that share little beyond a name.
What does this pay actually buy where I live?
A smaller wage in a cheaper place is not automatically less. Adjusted for local prices, this is worth $91,185.
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 $90,141 of this wage survives to your account.
Why is this job missing from some states?
Because the survey suppresses a figure when too few employers report it. This occupation has published pay in 48 states — the rest are withheld to protect confidentiality, which is not the same as nobody doing the work there.
What drives the percentile dispersion in this occupation?
Dispersion between the tenth percentile ($78,760) and the ninetieth ($172,830) exceeds the family median dispersion. SOC codes aggregate roles differing in seniority, industry and specialisation, and BLS does not disaggregate below the detailed occupation level, so within-title variance is not separable from the published series.
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 $91,185 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 $90,141 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 48 of the fifty-one jurisdictions. Suppression reflects sample size and confidentiality rules, and cannot be read as an absence of employment.
