BLS OEWS Wage Percentiles Explained: What the 10th, 50th, and 90th Really Mean
A friend once showed me a job posting and said, "The BLS says this job pays $58,000, so the offer is fair, right?" The posting was for an entry-level role, and the $58,000 was a median. Half the workers in that occupation earned less. He was comparing his starting salary to the midpoint of everyone's salary and talking himself into an underpaid offer. BLS OEWS wage percentiles explained properly would have saved him the trouble, because the percentiles are where the useful information lives.
What a percentile actually is
BLS defines it plainly: a percentile wage is the wage below which a certain percentage of workers fall. That is the whole definition, and it is worth sitting with for a second, because people consistently read it backwards.
BLS's own example. For an occupation with a 90th percentile hourly wage of $29.00: 90 percent of workers earn less than $29.00 per hour, and 10 percent earn more. The 50th percentile, the median, splits the workforce in half. The 10th percentile is the floor of the normal range, not the minimum wage for the occupation.
The five numbers BLS publishes, 10th, 25th, 50th (median), 75th, and 90th, sketch the shape of pay in an occupation. Read them as a ladder:
- 10th percentile: where the bottom of the normal range sits. New entrants, low-cost markets, part-time heavy mixes.
- 25th percentile: the lower quartile. Early-career, or experienced workers in cheaper metros.
- 50th percentile (median): the midpoint. Half above, half below. Not the average.
- 75th percentile: the upper quartile. Experienced, skilled, good markets.
- 90th percentile: the top of the normal range. Specialists, senior people, hot markets. Ten percent still earn more.
Why the spread beats the average
Two occupations can share a median and offer completely different careers. BLS has shown this directly: film and video editors have highly variable wages while other occupations with similar medians have flat distributions. The median hides that. The gap between the 10th and 90th reveals it.
This matters for negotiation. If the 90th percentile is triple the 10th, the occupation rewards skill, specialization, or market choice, and there is real upside to chasing the top. If the band is narrow, the median is nearly the whole story, and the negotiation is mostly about which side of the middle you land on. I check the spread before I check the median now.
One more BLS tip worth knowing: where you should expect to fall on the ladder depends on you. BLS's own guidance puts early-career workers near the 10th or 25th percentile and experienced workers near the 75th or 90th. Your percentile target is a function of your experience, not your ambition.
Percentiles vs the mean, and why both sites publish both
The mean (average) and the median answer different questions. The mean is total wages divided by workers; a handful of very high earners can drag it well above what a typical worker makes. The median is the middle worker. In right-skewed occupations, and most of them are, the mean sits above the median.
For negotiations, the median is usually the honest anchor, and the percentiles are the honest range. If you want the full version of that argument, the median vs mean piece goes deeper.
Putting it to work
When I research a role now, I pull the five percentiles for my metro and plot where I sit. If I am at the 25th with five years of experience, I am underpaid and I know exactly how underpaid. If I am at the 75th, I know the next jump is to the 90th, and I can see in dollars what that jump is worth. The median alone could never tell me either of those things.

FAQs
What does the 90th percentile wage mean in BLS OEWS data?
It is the wage below which 90 percent of workers in the occupation fall, so 10 percent earn more. It is not the top wage or the maximum; it is a realistic target for experienced, high-performing workers in the occupation.
Is the median wage the same as the average wage in BLS data?
No. The median (50th percentile) is the middle value: half earn more, half earn less. The mean can be pulled up by a few very high earners. In right-skewed occupations the mean sits above the median.
Which percentile should I use in a salary negotiation?
Match your experience: early-career candidates near the 10th to 25th percentile, mid-career near the median, experienced specialists near the 75th. Anchor to the percentile that fits you, not the median by default.
Where can I download BLS OEWS percentile wage data by metro area?
