What this pays, and what it is worth
- Delaware is one of the better-paying states for this job. The middle earner takes $101,380, which ranks 6 of 49 states with published figures. That is about 19.81% above the national middle.
- Within Delaware this is well-paid work. Of 445 occupations with published figures in the state, this job ranks 70 — in the top quarter of everything people do there.
- No great distortion either way. Delaware costs about what the country costs, so from $101,380, take-home of $74,691 is worth roughly $75,253 in national money. The average comes to $108,550, above the middle, thanks to the top of the range.
- Delaware ranks 6 of 49 states publishing a median for biological science teachers, postsecondary, at $101,380 — about 19.81% 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.
- Ranked against every occupation Delaware publishes a median for, biological science teachers, postsecondary sits 70 of 445 — the upper quartile of the state's wage distribution. National standing and within-state standing are separate questions, and a job can occupy very different positions on each.
- Price parity in Delaware is near the national base, so for biological science teachers, postsecondary, whose median is $101,380, the adjusted figure of $75,253 differs little from $74,691 retained after tax. The state's position for this occupation is therefore set by wage and tax rather than by living costs. At $108,550 the mean overshoots the median — the usual right-skewed shape.

Sources and assumptions
- Treat $101,380 as a midpoint for Delaware, not a promise. The tenth percentile is $63,780 and the ninetieth is $161,320 — a wide band, and where you land in it depends on far more than the state.
- That $74,691 take-home in Delaware comes from $101,380. 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 70 of 445.
- Two cautions on $75,253, the adjusted value of that $101,380 median. It levels out prices with a single number for all of Delaware. 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 70 of 445 locally.
- The Delaware median of $101,380 describes the midpoint of a distribution spanning $63,780 to $161,320. 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 $74,691, from $101,380, assumes a single Delaware 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 70 of 445 locally, and the state ranks 6 of 49 for it.
- This $75,253 adjusted figure, worked from $101,380, 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 70 of 445 in the state. The occupation ranks 70 of 445 locally.
Questions people ask
Is this the average pay for the job?
Half earn more than this and half earn less. The average sits at $108,550 because a long tail of high pay lifts it, so the two answer different questions.
Why is the pay range for this job so wide?
Because one job title covers very different work. The bottom tenth here earn $63,780 and the top tenth $161,320 — experience, employer and specialism separate them, and a single figure hides all three.
What does this pay actually buy where I live?
More than the figure suggests. Prices in Delaware sit below the national level, so take-home here stretches like $75,253 would elsewhere. The wage is the same; the ground it covers is larger.
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 Delaware adds its own income tax on top — which is why $74,691 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 49 states — the rest are withheld to protect confidentiality, which is not the same as nobody doing the work there.
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 Delaware is $108,550. 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 drives the percentile dispersion in this occupation?
Dispersion between the tenth percentile ($63,780) and the ninetieth ($161,320) 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?
Delaware'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 $75,253 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 $74,691 reflects federal income tax, OASDI, Medicare and Delaware 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 49 of the fifty-one jurisdictions. Suppression reflects sample size and confidentiality rules, and cannot be read as an absence of employment.
