BLS metro-level wage data places Mathematical Science Teachers, Postsecondary pay in St. Louis, MO-IL at a median of $83,390 per year, drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $79,940, St. Louis pays +4% above, signaling either concentrated employer demand, a cost-of-living premium, or both. Approximately 280 mathematical science teachers, postsecondarys are employed across the St. Louis MSA in SOC 25-1022.

The St. Louis pay distribution spans from $51,550 at the 10th percentile to $156,770 at the 90th — a 3.0× 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 $62,920 and the 75th at $116,250, so half of St. Louis-based mathematical science teachers, postsecondarys 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 St. Louis, MO-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 MO data, and peer-metro comparisons — a median is a starting point, not a ceiling.
