BLS metro-level wage data places Crushing, Grinding, and Polishing Machine Setters, Operators, and Tenders pay in Sioux City, IA-NE-SD at a median of $58,670 per year ($28.21/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $48,540, Sioux City pays +21% above, signaling either concentrated employer demand, a cost-of-living premium, or both. Approximately 70 crushing, grinding, and polishing machine setters, operators, and tenderss are employed across the Sioux City MSA in SOC 51-9021.

The Sioux City pay distribution spans from $48,330 at the 10th percentile to $63,280 at the 90th — a 1.3× 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 $48,330 and the 75th at $60,860, so half of Sioux City-based crushing, grinding, and polishing machine setters, operators, and tenderss 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 Sioux City, IA-NE-SD 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 IA data, and peer-metro comparisons — a median is a starting point, not a ceiling.
