Резюме	The child-woman ratio is the number of young children, usually those under five, per woman of reproductive age in a population. Computed from a single census age-sex distribution, it is the simplest indirect indicator of fertility, designed for settings where birth registration is absent or unreliable. Because young children are the surviving product of recent births, their number relative to potential mothers serves as a rough proxy for the level of childbearing over the preceding few years.	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.
