Kokkuvõte	Paleodemographic analysis reconstructs the demographic life of past populations — their mortality schedules, life expectancy, age structure, and fertility — from the age-at-death distributions of skeletal samples. It begins from the per-individual ages produced by osteological estimation and aggregates them into life tables or, increasingly, fits formal mortality models. The field was reshaped by Bocquet-Appel and Masset's bracing 1982 critique, 'Farewell to Paleodemography,' which exposed two fatal biases: the tendency of skeletal age estimates to mimic the age structure of the reference sample rather than the target population, and the corrupting effect of age-estimation error. The modern response, developed by the Rostock School and others, abandons naive life tables in favor of hazard models and Bayesian estimation that treat the observed data as the noisy product of a true mortality schedule.	The number of identified specimens, universally abbreviated NISP, is the most basic quantitative measure in zooarchaeology: a simple count of every bone or bone fragment that an analyst can identify to a taxon. It is the first number computed for almost any faunal assemblage because it is fast, transparent, additive across deposits, and reproducible. Yet, as Reitz and Wing emphasize and Lyman dissects in detail, NISP is an observation count rather than an animal count, and it is distorted by fragmentation, by recovery technique, and by the fact that fragments of a single bone are not independent of one another. Understanding precisely what NISP does and does not measure is the foundation on which all other faunal abundance estimates rest.
