The pay ranking everyone shares hides three things

Once a year a familiar list circulates: Korea’s best-paying employers, one company per row, one number per company. It is easy to share and easy to argue about. It is also, as a way to understand pay, almost designed to mislead — because a single figure per company throws away the three things that actually decide what work pays.

We build from Statistics Korea’s establishment survey, and the house rule here is blunt: we report distributions, not averages. A ranking is an average dressed as a verdict. Here is what it buries.

One: the distribution inside the number

A company’s “average pay” is a single point on a wide spread. Report the average and you erase the range — who is at the bottom, how far the top sits above the middle, whether the typical worker looks anything like the mean. The same logic runs across the whole economy, not just one firm: bigger firms pay more at every step, and the gap widens as you climb the size ladder. A league table of headline averages hides that staircase inside each row.

Two: the gap the average absorbs

The single number quietly assumes everyone in the building is on the same kind of contract. They are not. Temporary and daily workers earn about 39% of what regular staff make — roughly 1.74m against 4.47m won a month — and that gap has barely moved in over a decade. Blend the two into one company average and the ranking rewards a firm for a number most of its workers never see. Who is counted, and who is averaged away, changes the answer more than the rank does.

Three: the hours the number never shows

Monthly pay is pay-per-month, not pay-per-hour — and the hours underneath have been moving. Korea’s monthly working time fell about 13% since 2011, mostly through fewer days rather than shorter days. Two firms with the same headline pay can demand very different amounts of a worker’s life for it. A pay ranking that never divides by hours is comparing prices without checking what is in the basket.

Why we won’t rank it for you

We could publish our own single-number pay league table. We don’t, for the same reason we describe market value as capital intensity rather than productivity: a ranking is a compression, and this particular compression throws away exactly the parts — the spread, the gap, the hours — that tell you whether a job is actually good. We would rather hand you the distribution and let you read it. This is a statistic, not you.

The debate

So: is “which company pays the most” a fair way to rank employers, or does one number per company flatter the top and bury everyone the average swallowed? A rank is easy; a distribution is honest. What do you think? This is a talking point, not a verdict — argue it out below.

A fresh top-pay ranking this week shows the same average hiding a gender split — every reproducible company in it pays men more.
