A population pyramid is a graphical illustration of the age distribution of a population. The shape of the population pyramid varies with birth rate, death rate and mobility as a result of migration. The population pyramid of Hong Kong does not fit into any standard shape. The group tip reflects an increase in elderly population while a contracted base is contributed by a low birth rate. Health correlation and mobility patterns have also shaped the pyramid, with slight variation across districts.

人口金字塔是反映地區人口和年齡性別比例的圖像,形狀像金字塔。金字塔的形狀隨著出生率、死亡率和人口流動而轉變。圖示香港的年輕人口數目減少,導致金字塔底部縮窄,而人口老化又令金字塔頂部擴大。金字塔的變形,當中可能受人口健康和流動狀況影響。
