What is a Median Age?

A population's median age is the age at which half of its members are younger than it and the other half are older, creating two numerically equal groups. It is a measurement of the age distribution's central tendency within a population.

How is Median Age Calculated?

In order to get the median age, one must first make a list of every age in a given population and then sort them by ascending order. The age that precisely lies in the center of this list is known as the median age. The median is the mean of the two middle ages if the number of ages is even.
