| Location | Average (Median) Age in 2021 |

This higher median age suggests that Lewes is home to a relatively older demographic compared to the wider region and country.
Understanding Median Age
When discussing "average age" in census data, the term "median age" is often used. The median age is the age that divides a population into two equal halves: half the people are younger than this age, and half the people are older. It provides a more robust measure of central tendency for age distribution than the arithmetic mean, as it is less affected by extreme values (very young or very old individuals).
