요약	The Coale-McNeil model is a parametric description of how first marriages are distributed by age. Ansley Coale and Donald McNeil showed in 1972 that the age pattern of first marriage in widely different populations has a common shape, captured by a single standard curve that can be shifted and stretched. Three parameters — an origin age at which marriage starts, a scale that controls how spread out the process is, and the ultimate proportion who ever marry — reproduce almost any observed first-marriage schedule, giving demographers a compact and comparable summary of nuptiality.	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.
