What BLS Wage Data Actually Measures (and What It Deliberately Ignores)

The Bureau of Labor Statistics does not ask workers what they make. It asks employers. That single methodological choice shapes every number in the Occupational Employment and Wage Statistics (OEWS) program — what gets counted, what gets left out, and how confidently you can use the result in a salary conversation.

Before you look up the pay range for your occupation in your city, it is worth knowing exactly what that range is measuring.

Where the numbers come from: employer payroll records

The OEWS program mails surveys to roughly 1.1 million employer establishments over a three-year rolling cycle. Employers report the number of workers in each Standard Occupational Classification (SOC) code and the wages those workers received. The data are drawn from payroll records, not from workers' memories or self-estimates.

This matters for two reasons. First, payroll records are the same source employers use for tax filings, so they carry a level of internal discipline that self-reported figures lack. Second, the unit of observation is the job slot, not the person — a single employer with 200 registered nurses contributes 200 wage observations, which anchors the distribution in actual market pay rather than in whoever happened to fill out a survey on a salary-comparison website.

The result is a dataset covering roughly 155 million wage and salary jobs across the U.S. economy (SOC 00-0000, OEWS May 2025, published May 2026). That scale is why BLS percentiles hold up as a negotiation anchor in a way that crowd-sourced figures cannot. The guide Why Your Salary Negotiation Should Start with BLS Data, Not Glassdoor walks through that argument in detail.

What the wage figure includes

BLS defines "wages" for OEWS purposes as straight-time gross pay. That definition captures more than base salary:

• Base pay — the hourly rate or salary before any additions
• Production bonuses — incentive pay tied to output or performance that is paid regularly
• Commissions — included when they are part of the regular payroll cycle
• Shift differentials — the premium paid for evening, overnight, or weekend shifts
• Tips — reported by employers in industries where tip income is tracked on payroll

The practical effect is that the OEWS median for a tipped occupation like Waiters and Waitresses (SOC 35-3031) reflects more than a base hourly wage, and the wide spread in that occupation's distribution — from $18,100 at the 10th percentile to $64,720 at the 90th (OEWS May 2025) — captures real variation in how much tip income reaches payroll.

For sales roles, commissions that cycle through payroll are included. The 90th-percentile figure for Sales Representatives of Services (SOC 41-3091) reaches $148,840 annually (OEWS May 2025), a spread that partly reflects commission structures, not just base differences across employers.

What the wage figure deliberately excludes

The OEWS wage is not total compensation. Several high-value items are outside its scope by design:

• Equity and stock-based compensation — RSUs, options, and ESPP shares do not appear in payroll records in a form BLS can standardize across employers
• Employer-paid benefits — health insurance premiums, retirement contributions, and paid leave are excluded
• Irregular bonuses — year-end discretionary bonuses, signing bonuses, and one-time retention payments are not captured
• Overtime premium — overtime hours are excluded; only straight-time rates are counted
• Non-payroll income — self-employment earnings and independent contractor income are outside the survey frame entirely

For occupations where equity is a large share of total compensation — software roles, finance, executive positions — the OEWS figure can look low relative to what workers in those roles actually take home in a strong year. The median for Software Developers (SOC 15-1252) is $135,980 annually (OEWS May 2025), but that figure does not include RSU vesting schedules that can add tens of thousands of dollars at large technology employers.

This is not a flaw in the data. It is a defined scope. The OEWS is measuring the wage labor market, not total wealth transfer from employer to employee.

A worked example: what the distribution actually tells you

Take Registered Nurses (SOC 29-1141), one of the most commonly benchmarked healthcare occupations.

From the OEWS May 2025 estimates (published May 2026):

• 10th percentile: $68,940
• 25th percentile: $80,330
• Median (50th): $97,550
• 75th percentile: $112,350
• 90th percentile: $137,470

Those figures reflect straight-time payroll wages for 3,379,720 employed registered nurses nationwide. Shift differentials for night and weekend work are included. Employer-paid health benefits, retirement matches, and any equity grants are not.

A hospital's total compensation package might look quite different from these figures. But the OEWS distribution tells you where the wage floor and ceiling sit for this occupation across the actual labor market — information that is harder to game than a self-reported average on a comparison site.

Geography reshapes this distribution substantially. The OEWS publishes metropolitan-area estimates alongside national ones, and the same SOC code can carry very different percentile ranges depending on the metro. The guide The Metro Area Trap: Why the BLS Definition of Your City Might Not Match Your Cost of Living explains how BLS defines metropolitan statistical areas and why the boundary matters before you trust a local figure.

The classification layer: SOC codes and what they hide

BLS assigns every job to a six-digit SOC code before computing wages. The code is the unit of analysis, which means the wage distribution for a code reflects everyone classified there — regardless of what their employer calls the role.

A company that calls a role "Senior Software Engineer" and one that calls it "Software Engineer II" may both map to SOC 15-1252 (Software Developers). The OEWS distribution captures both. That is useful when you want a market-level view, but it means the BLS figure will not separate senior from junior within a code. The within-code spread — that gap from the 10th to the 90th percentile — is partly driven by experience and seniority differences that the SOC system does not subdivide.

When you use the Salary Percentile Lookup to find where your pay sits in the distribution, the percentile position is a reasonable proxy for where you stand relative to your peers in that SOC code — but it cannot tell you whether the gap is driven by experience, employer size, geography, or something else.

Frequently asked questions

Does BLS OEWS include bonuses in its wage figures?

It includes production bonuses, commissions, and shift differentials when they are paid through regular payroll cycles. Irregular bonuses — discretionary year-end payments, signing bonuses, and retention awards — are excluded because they do not appear consistently in the payroll records employers submit.

Why doesn't BLS include equity compensation like RSUs?

Equity grants are excluded because they are not a payroll wage in the period they are granted, and their realized value depends on stock price at vesting — a figure that varies by employer, grant date, and market conditions in ways that cannot be standardized across the millions of establishments the OEWS surveys.

How current is the BLS OEWS data on this site?

The figures served by the Salary Percentile Lookup reflect the May 2025 OEWS estimates, published by BLS in May 2026. BLS releases OEWS data annually, so this is the most recent vintage available as of this guide's publication date.

Are self-employed workers included in BLS OEWS figures?

No. The OEWS surveys employer establishments and covers wage and salary workers only. Independent contractors, freelancers, and the self-employed are outside the survey frame. If a significant share of an occupation works independently, the OEWS distribution reflects only the employer-employee segment of that labor market.

Can I use the BLS median as my salary target in a negotiation?

The BLS median tells you where the midpoint of the wage distribution sits for your SOC code — not what you specifically should earn. It is a defensible, employer-recognized floor for a negotiation conversation, but your position in the distribution depends on experience, geography, employer size, and factors the OEWS does not capture. Use the percentile range, not just the median, to understand the full spread.
