요약	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.	The gross reproduction rate is the average number of daughters a woman would bear over her lifetime if she experienced a given set of age-specific fertility rates and survived through all her childbearing years. It is a single-sex reproduction measure: by counting only daughters, it tracks how a generation of women replaces itself, ignoring the mortality that would thin the next generation. As such it sits between the total fertility rate, which counts all children, and the net reproduction rate, which discounts daughters for the chance of dying before they themselves reproduce.
