What it pays vs. what it buys

About this page
This page reports national wage data for Bus and Truck Mechanics and Diesel Engine Specialists (SOC 49-3031) from the Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) survey. OEWS is the federal government's primary source for occupational wage data — a nationally representative survey of employers conducted annually, covering approximately 1.1 million establishments. All figures reflect the most recent May reference period available via the BLS public API.
The headline number is the annual median wage — the wage at which half of all workers in this occupation earn more and half earn less. The median is the right benchmark for most workers because it is not inflated by the top earners the way the mean (average) is. The 90/10 ratio compares the top decile (p90) to the bottom decile (p10): a ratio of 3.0 means workers at the 90th percentile earn three times those at the 10th percentile.
Bus and Truck Mechanics and Diesel Engine Specialists is classified under 49-0000 Installation, Maintenance, and Repair Occupations, placing it alongside other occupations in that sector of the labor market. BLS estimates total national employment in this occupation at approximately 289,960 workers. The wage spread shown in the percentile table is the bargaining-surface map your employer operates from. Most employers know exactly where each of their workers sits in the band; most workers don't. That information asymmetry is what this page is designed to close.
The 90/10 ratio is used as an implicit "bargaining power metric" here, but it measures structural spread — not your individual leverage. High ratio occupations have wide bands and more room to negotiate; narrow-ratio occupations are often governed more by title and tenure than by individual negotiation. Methodology at /methodology#oews-salaries.
OEWS data does not include equity, bonuses, benefits, or total compensation — only base wages. The true compensation gap is wider than what these numbers show. These are the floor numbers, not the ceiling. Federal law in many states also prohibits employers from asking about your current salary during hiring; knowing the market rate is the countermeasure.
