The midpoint age that separates the younger half of a population from the older half
The age for a specific population that divides the population into two equal parts For grouped census data, the median age is calculated by interpolation between the upper and lower limits of the age group where the cumulative sum of age groups reaches 50%
In a list of ages arranged from youngest to oldest, the median age is in the centre; half of the ages in the list are below the median and half are above it
A calculation that divides the age distribution of the population into two equal groups, with one-half of the population older, and one-half younger, than the figure show
