Population pyramid  (POPULATION pyramid)


The age distribution of a population is either given by individual years of age1 or by age groups2, which may be quinquennial age groups3 or quinary age groups3, or broad age groups4, such as 0-19 years, 20-59 years, 60 years and over. Occasionally a population’s age distribution6 or age structure6 is given by classifying the population by year of birth5. Graphically an age distribution may be represented by a population pyramid7 which is a histogram (155-8) showing the population by age and sex and so named because of its pyramidal shape.
