BLS metro-level wage data places Correctional Officers and Jailers pay in Joplin, MO-KS at a median of $35,200 per year ($16.92/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $58,940, Joplin pays 40% below, which typically tracks with a lower local cost of living or smaller specialized-employer cluster. Approximately 90 correctional officers and jailerss are employed across the Joplin MSA in SOC 33-3012.

The Joplin pay distribution spans from $31,460 at the 10th percentile to $49,610 at the 90th — a 1.6× 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 $34,740 and the 75th at $35,200, so half of Joplin-based correctional officers and jailerss 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 Joplin, MO-KS 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.
