How are South Dakota Plumber salaries calculated on this page?

Nominal wages come from BLS Occupational Employment and Wage Statistics (OES) — annual employer surveys, May 2026 reference period. Real-wage figures use BEA Regional Price Parities (2023 vintage) to adjust for state-level cost of living. No self-report or jobs-board data is mixed in.

What does the top of the Plumber pay scale look like in South Dakota?

The 90th percentile lands at $75,290. That tier typically reflects senior roles, specialty certifications, high-cost-of-living metros within the state, or union-negotiated rate cards. Below that, the P75 quartile is $63,260.

How many Plumbers does South Dakota employ?

BLS OES counts 1,800 Plumbers employed in South Dakota in the most recent release. Employment density relative to population determines whether wage tiers reflect a robust competitive market or a thinner labor pool.

Why is the BEA RPP for South Dakota different from a single CPI number?

Is South Dakota a 'real-wage arbitrage' state for Plumbers?

The premium is concentrated in industrial, commercial, and government project work; residential service plumbing in South Dakota is predominantly non-union. UA Local hall job boards in South Dakota are the cleanest reference for current scale and benefit values.

Service plumber vs new construction plumber in South Dakota — pay difference?

BLS aggregates plumbers, pipefitters, and steamfitters (47-2152) into one category. In South Dakota, residential service plumbers (drain cleaning, water heater replacement, repair calls) earn near or below BLS median; commission-based service models in South Dakota can produce above-median earnings for high-volume techs but with substantial variance. New-construction plumbing in South Dakota pays above median for pipefitter and steamfitter specialties on industrial and commercial projects, especially when union-rate prevailing-wage rules apply on government work.
