Tracking Year-Over-Year Trade Wage Changes (and Why It Matters)

When Last Year's Number Becomes This Year's Mistake

You made a solid offer six months ago. Journeyman electrician, $28 an hour — fair at the time, maybe even a little above what you'd been paying. The candidate took it.

Now you're posting the same role again, and the first two applicants you phone-screen laugh at the number. One of them says he's seen $33 posted at the shop across town. The other tells you politely that he'll wait.

Nothing changed about the job. What changed is the market rate — and you didn't catch the move.

That's the real cost of treating wages as a set-it-and-forget-it line item. Trade wages don't drift; they shift, sometimes sharply, and the shift happens whether or not you're watching. This article walks through what year-over-year trade wage changes actually measure, where the authoritative data comes from, and how to build a lightweight tracking habit that keeps your offer schedule from going stale.

What "Year-Over-Year Trade Wage Changes" Actually Measures

Year-over-year (YoY) wage change is simply the difference between what a role paid in one annual snapshot and what it pays in the next. It's expressed as a percentage increase (or, rarely, a decrease) and tells you the direction and speed of the market.

Two government datasets own this measurement for US trades:

BLS Occupational Employment and Wage Statistics (OEWS). Published every spring, the OEWS covers more than 800 detailed occupations at the national, state, and metro level. Every OOH wage figure you've ever seen — electrician median, plumber median, HVAC tech median — traces back to this survey. It's built from roughly 1.1 million employer establishments sampled over a three-year, six-panel rolling window, covering an unweighted 84.7 million jobs (roughly 55 percent of national employment). That sample depth is why it's authoritative. It's also why the numbers move deliberately rather than week to week — you're looking at a labor market average, not a job-board snapshot.

Employment Cost Index (ECI). Published quarterly by BLS, the ECI measures the rate of change in wages and salaries for private industry, independent of employment-mix shifts. It's the cleanest single number for answering "how fast are wages rising right now?" — because it controls for the fact that the workforce composition itself is changing.

Together, OEWS gives you the level (what does an electrician actually earn?) and ECI gives you the velocity (how fast is that level moving?). You need both to run an informed offer schedule.

For a deeper look at when new OEWS data drops and how to read it when it does, see our BLS OEWS release schedule guide.

What the Current Numbers Show

The level: where trade wages sit today

The May 2024 BLS OEWS (the most recent confirmed release at time of writing — [VERIFY whether May 2025 is now live at bls.gov/oes]) shows the construction and extraction occupational group carrying a median of $58,360 per year, compared with $49,500 for all occupations. That's a gap of nearly $9,000 — trade work pays materially more than the economy-wide midpoint.

Breaking it down by trade (all figures BLS, May 2024, national):

Trade	SOC Code	Median Annual Wage
Plumbers, pipefitters & steamfitters	47-2152	$62,970
Structural iron & steel workers	47-2221	$62,700
Electricians	47-2111	$62,350
Sheet metal workers	47-2211	$60,850
Carpenters	47-2031	$59,310
HVAC mechanics & installers	49-9021	$59,810
Construction equipment operators	47-2073	$58,320
Masonry workers	—	$56,600
Welders, cutters, solderers & brazers	51-4121	$51,000

These are national medians — the midpoint, meaning half the workforce earns more and half earns less. Your local number may be higher or lower depending on your metro and state. For the specific figure that applies to your location, go to bls.gov/oes and filter by SOC code and geography. The multi-trade wage comparison guide walks through how to read those tables side by side.

The velocity: how fast wages are moving

Here's where the ECI comes in.

Private-industry wages and salaries rose +3.4% year-over-year as of March 2026 (ECI — [VERIFY against latest BLS ECI release at bls.gov/eci]). Union workers saw +4.3% YoY as of December 2025; non-union workers saw +3.3% YoY over the same period (ECI — [VERIFY]). Total compensation (wages plus benefits) grew +3.4% YoY as of December 2025, compared with +3.8% YoY at December 2024 — so the pace of growth has moderated slightly, but it remains well above the historical norm for construction labor (ECI — [VERIFY]).

What does +3.4% mean in dollar terms? On a $62,350 electrician median, that's roughly $2,120 added to the annual midpoint in a single year. An offer anchored to last year's number without adjustment is starting the negotiation $2,000 behind before the candidate says a word. For a worked example of how that math flows through a salary band (minimum / midpoint / maximum), see our skilled trades wage benchmarking guide.

Important note on per-trade YoY percentages: The verified-data library for this article carries the ECI economy-wide and union/non-union splits above. The BLS does not publish a separate annual ECI series broken out by individual trade occupation (electricians only, HVAC only, etc.). To track YoY movement for a specific SOC code, the right method is to compare the OEWS May release from one year to the next. That comparison requires two confirmed annual releases; where only May 2024 data is confirmed in this library, the per-trade velocity figures are covered qualitatively. Always confirm at bls.gov/oes.

Why Trades Are Running Hotter Than the Rest of the Economy

The wage growth in trades isn't random — it's structural, and knowing the structure helps you anticipate where rates go next rather than just chasing them.

Supply is contracting while demand is expanding. The construction industry needed an estimated 439,000 net new workers in 2025, and will need an estimated 349,000 more in 2026 (Associated Builders and Contractors). Over the next decade, an estimated 1.9 million workers will need to be attracted to the industry just to keep pace with growth and retirements. Meanwhile, roughly one in five construction workers is already over age 55 — a retirement wave already underway. That's a durable supply squeeze, not a spike.

Trade growth is running at roughly three times the economy. Electricians are projected to grow +9% from 2024 to 2034; HVAC mechanics +8%. The construction and extraction group as a whole is adding roughly 649,300 annual openings. The economy-wide employment growth projection over the same period is +3.1%. When your occupation is growing three times faster than average, competition for every qualified hire is structurally more intense — and wages reflect that. For more on what's driving the shortage, see our labor shortage overview for 2026.

Union wage settlements are pulling non-union rates up. The 4.3% union YoY figure (ECI, December 2025 — [VERIFY]) represents negotiated floor increases that set a visible market reference. Non-union contractors in the same metro often have to match or approach those increases to avoid losing technicians to union shops. The reasons tradespeople leave for pay follow a predictable pattern — and a visible gap to a union scale is near the top of it.

How to Track Year-Over-Year Trade Wage Changes Without Drowning in Spreadsheets

The raw OEWS data is free at bls.gov/oes. The problem isn't availability — it's usability. A full OEWS download is a tab-delimited flat file covering 800+ occupations across national, state, and 530-plus metro areas. Finding the SOC code for your trade, filtering to your geography, and then building a comparison to last year's release takes the better part of an afternoon — and that's before you turn a raw percentile into a salary band your hiring manager can actually use.

A practical tracking cadence looks like this:

1. Pick your SOC codes. One per trade you hire (see the table above for the right codes). If you hire across multiple trades, the multi-trade wage comparison guide has a primer on reading multiple SOC series together.

2. Pull the same geography each cycle. National is the baseline. Your state is the next layer. Your metro is the most actionable — but check whether BLS suppresses the estimate for your MSA (metropolitan statistical area — the BLS's name for a major metro labor market). Suppression happens when the local sample is too small to meet publication standards; if your metro is suppressed, fall back to the state figure and say so internally.

3. Record the percentiles, not just the median. The 25th percentile (where 3 out of 4 workers earn more) anchors your entry-level minimum. The 75th percentile (where 3 out of 4 workers earn less) sets your target for competitive senior-level hires. Tracking how each percentile moves year-over-year tells you whether compression is happening at the top or the bottom.

4. Apply the ECI as an interim adjustment. Between annual OEWS releases, use the current ECI rate as a directional signal. If wages and salaries grew +3.4% this year, your May 2024 benchmark has probably moved roughly that much — and your offer anchor should reflect it.

5. Set a calendar reminder for the OEWS release. The BLS typically publishes the May reference-year data in the spring of the following year. The BLS OEWS release schedule guide shows the expected publication window so you can pull new data as soon as it drops, not six months later.

SkilledMarkets automates steps 1 through 4 — pulling the current OEWS release by SOC code and geography, joining it to the O*NET occupational profile for every trade, and generating a min/midpoint/max salary band in the format your next offer letter needs. See what's included and how it's priced.

The Real Cost of Not Tracking

This isn't an abstract risk. When an offer is anchored to a wage that's 12 or 18 months old in a market that has moved +3–4% annually, you're operating with a structural disadvantage every time a candidate counters.

According to SHRM benchmarks, replacing an employee costs 50%–200% of their annual salary — and that's before you factor in the productivity gap while the role sits open. On a $62,000 journeyman electrician, a mid-range estimate puts the replacement cost at $31,000–$62,000 per turnover event. A mis-priced offer that drives a qualified candidate to a competitor, or that lands a hire who leaves within six months because they quickly discover the market pays more, generates that cost more than once. These are illustrative ranges based on published SHRM benchmarks — verify against your own cost-per-hire data before using them in internal planning.

The wage data that prevents this situation is free and public. What costs time is turning it into an answer you can act on before the candidate's next interview.
