BLS metro-level wage data places Social and Human Service Assistants pay in Sumter, SC at a median of $36,800 per year ($17.69/hr/hour), drawn from the OEWS May 2025 release for this Metropolitan Statistical Area. Compared to the national median of $45,930, Sumter pays 20% below, which typically tracks with a lower local cost of living or smaller specialized-employer cluster. Approximately 90 social and human service assistantss are employed across the Sumter MSA in SOC 21-1093.

The Sumter pay distribution spans from $30,280 at the 10th percentile to $49,970 at the 90th — a 1.7× 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 $33,180 and the 75th at $44,100, so half of Sumter-based social and human service assistantss 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 Sumter, SC 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 SC data, and peer-metro comparisons — a median is a starting point, not a ceiling.
