Sažetak	The Preston-Coale method, also called the synthetic extinct generations method, estimates the completeness of death registration by rebuilding a population from the very deaths it records. Introduced by Samuel Preston and Ansley Coale in 1982, it uses the variable-r relations of a non-stable population to project each age group's future deaths forward, growth-adjust them, and accumulate them into the number of people who must currently be alive at each age. Comparing this implied population with the observed census count reveals what fraction of deaths the vital system actually captures.	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.
