Observed pay change
What changed, BLS OEWS 2019–2025
- The published national median for Engine and Other Machine Assemblers moved from $45,660 in May 2019 to $53,710 in May 2025 (+17.6%).

Engine and Other Machine Assemblers (SOC 51-2031) has a national median of $53,710 per year in the BLS Occupational Employment and Wage Statistics May 2025 release. The published 10th-to-90th-percentile boundaries run from $38,500 to $77,750, and the published mean is $57,790. Those summary statistics describe the estimated distribution; their difference alone does not identify its cause. OEWS estimates 34,000 jobs in covered establishments nationally. WageDex has published rows for 35 state or territory areas and 56 metropolitan or nonmetropolitan wage areas. The published national median moved from $52,540 in the May 2024 OEWS release to $53,710 in May 2025, a rise of $1,170 (+2.2%). This is a change between two BLS survey estimates, not an inflation-adjusted same-worker pay raise.
BLS Employment Projections forecast a -21.1% change in employment from 2024 to 2034, which we classify as declining relative to the all-occupations baseline of 3.1%. About 2,800 openings are projected per year from growth, occupational transfers, and labor-force exits. BLS assigns High school diploma or equivalent as typical education needed for entry, and BLS classifies its typical on-the-job preparation as moderate-term on-the-job training. BLS does not publish a separate occupation-specific fatality and injury rate for this role in the current release. The safety panel below shows its broad Production Occupations SOC-group context and is not an occupation-level measurement or ranking.
Geographic variation matters as much as the headline median. Ohio pays the highest state median at $74,750, which is +39% above the national figure. The highest published metropolitan-area median in this ranking is Seattle-Tacoma-Bellevue, WA at $102,530. The observed difference does not identify its cause. Pair the national median with the state and metropolitan-area rows below while keeping the geography and statistic consistent. OEWS includes tips, commissions, incentive pay, and production bonuses, but not employer benefits, overtime premiums, stock compensation, or nonproduction bonuses. See our methodology for the sourcing and calculation details.

Across the 11 releases WageDex holds for this occupation, the published national median went from $39,600 in May 2015 to $53,710 in May 2025. Within the SOC-2018 classification (2019–2025), the like-for-like change averages +2.7% per year in nominal terms. Within the same SOC classification, estimated employment went from 45,980 in May 2019 to 34,000 in May 2025.
Each figure is a separate BLS survey estimate, so a change between releases reflects the estimated occupation-wide median in each year. It is not the raise any individual worker received, and it is not adjusted for inflation. Years where BLS did not publish an annual median for this occupation are omitted rather than filled in. This span also crosses a classification change: releases before May 2019 use the 2010 Standard Occupational Classification and later releases use the 2018 SOC, so figures either side of that boundary are not strictly like-for-like. Headline change rates on this page use only the same-classification subset.
