요약	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.	Stable Population Theory is a mathematical framework in demography that describes the age structure and growth dynamics of a closed population subject to constant age-specific fertility and mortality schedules over a long period. Foundational work by Alfred J. Lotka established the core integral equation in the early twentieth century, and Ansley Coale's 1972 mathematical synthesis became the definitive theoretical reference, showing that any population exposed to invariant vital rates will converge to a unique stable age distribution growing at a fixed intrinsic rate of natural increase.
