Tóm tắt	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.	A life table is a systematic, age-structured summary of the mortality experience of a population. It traces a hypothetical cohort of births — conventionally 100,000 — through successive age intervals, recording how many survive, how many die, and how many person-years are lived at each interval. The method was formalized in its modern probabilistic form by Chiang (1984), synthesizing centuries of actuarial and demographic practice into a rigorous statistical framework applicable to human and biological populations alike.
