Nominal medians: BLS OEWS, May 2024 estimates (published April 2025) — occupational wage benchmarks across all workers, not MBA-specific outcomes. Adjusted column: SalaryMBA estimate, computed as nominal ÷ (state RPP ÷ 100) using BEA RPP 2024 all-items regional price parities. An adjusted figure is a purchasing-power comparison, not a wage anyone is paid.

|---|---|---|
| 10th percentile | $67,240 | Entry / early-career end |
| 25th percentile | $85,660 | |

| 75th percentile | $158,880 | |
| 90th percentile | $199,130 | Senior / top-market end |
Other MBA-relevant roles in Illinois
How to read the Illinois number
The $106,560 median means half of Data Scientists in Illinois earn less and half earn more. It is measured across everyone in the occupation — every level of experience, every industry, and every level of education. It is not the salary of a recent MBA graduate, and it is not a starting salary.
BLS counts roughly 10,520 people in this role in Illinois. The national percentile spread above is the more useful planning tool: within a single occupation, the distance between the 10th and 90th percentile typically dwarfs the difference between states. Where you land inside that range is driven far more by industry, function, and seniority than by geography.
What this data can and cannot tell you
This page answers “what does this role pay here.” It cannot answer “what will an MBA pay me here.” The BLS surveys establishments about occupations, not degrees, so no MBA premium can be isolated from it. Any site presenting these figures as MBA salaries is overstating what the source supports.
For MBA-specific figures we rely on cited school employment reports and moderated submissions, published only above our sample-size gates — see our methodology. To model your own economics, the MBA ROI calculator turns a target salary, tuition, and debt into a payback estimate.
