Ringkasan	Population pyramid analysis is the description and interpretation of a population's age-sex structure through a back-to-back horizontal bar chart, with males on one side, females on the other, and age groups stacked from youngest at the bottom to oldest at the top. The shape of the pyramid encodes a population's fertility, mortality, and migration history and is the demographer's first diagnostic of whether a population is young and growing, ageing, or contracting.	The age dependency ratio is a simple summary measure of a population's age structure that expresses the number of people in 'dependent' age groups — children and the elderly — relative to those of working age, conventionally per 100 working-age persons. It is split into a youth dependency ratio and an old-age dependency ratio, and it is among the most widely used demographic indicators of the potential economic burden an age structure places on its productive population.
