BLS metro-level wage data places Data Scientists pay in Champaign-Urbana, IL at a median of $91,760 per year ($44.11/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $120,230, Champaign-Urbana pays 24% below, which typically tracks with a lower local cost of living or smaller specialized-employer cluster. Approximately 140 data scientistss are employed across the Champaign-Urbana MSA in SOC 15-2051.

The Champaign-Urbana pay distribution spans from $67,240 at the 10th percentile to $134,920 at the 90th — a 2.0× spread that reflects experience tenure, specialization, employer size, and the difference between public-sector, nonprofit, and private-sector compensation inside the metro. The 25th percentile sits at $74,000 and the 75th at $121,750, so half of Champaign-Urbana-based data scientistss earn within that middle band.

Metro figures capture where you actually work, not just where you live — which matters for commuters. BLS draws metro boundaries from the OMB MSA definitions, so Champaign-Urbana, IL covers the central city plus outlying counties tied to the metro economically. Remember that OEWS wages reflect base pay only: employer-provided health insurance, retirement matches, stock options, signing bonuses, overtime, and tips are excluded and can add 20-40% to real total compensation. Before using this metro median as a negotiation anchor, triangulate against the same occupation's national profile (linked below), its state-wide IL data, and peer-metro comparisons — a median is a starting point, not a ceiling.
