Correct – a population-level income distribution graph has some people earning loads of money, whereas the majority earn much less. It is a classic example of a skewed distribution, specifically a “right-skewed” distribution. In this distribution, the mode (most common) will return the lowest value, the median (middle value) will be slightly higher and the mean will be highest as it is pulled to the right by the long tail.
