Analysis of Human Life Span through History

The problem of correctly interpreting data on the mean age of people’s death in different historical periods based on information presented in Wikipedia and included in the Personalities of the Encyclopedia Historical Database is considered. The specificity of these data associated with censoring and the nature of their collection that lead to selectivity is noted. An approach is proposed that takes into account these circumstances, which makes it possible to clarify the obtained patterns of life expectancy and expand the historical range of research.
