Median vs mean income.

In plain English

Median income is the value that splits households into two equal halves, while mean income adds every household's income and divides by the number of households. Because income is skewed, with a long tail of very high earners and a floor at zero, the mean almost always sits above the median. That gap is itself a rough measure of concentration: the wider it is, the more of the total sits at the top. Statistical agencies publish both, along with breakdowns by age, region, and household type. Which one a headline uses can change the story completely.

01Why it matters

If you are benchmarking your own pay or a town's affordability, the median tells you about a typical household while the mean tells you about the total pool, and using the wrong one can make an ordinary income look far behind.

02The math, step by step

Say five households earn $30,000, $40,000, $50,000, $60,000, and $820,000. The median is $50,000, the middle value. The mean is $1,000,000 divided by 5, or $200,000. Four of the five households earn well under the average, which is exactly the point.
