Why is age not normal distribution in statistics?
In a stable population, the number of people of any age must be smaller than the number of people in the age just below. This is because the difference between the two is the number of younger people who died at that age. Furthermore mortality rates are age dependent: after a relatively (or in some cases absolutely) high infant mortality, the rate drops until old age kicks in. As a reult the distribution is not normal. In a growing population the lower end of the distribution is large and so again not normal.
