Notability by year of birth. The mean number of language editions in which men and women are included as a function of their birth year. The global importance decreases with birth years, suggesting that less historic people are covered by Wikipedia in a more local way. This can be explained in part by the availability of information about these people, but also by the collective process whereby the editors of each language edition describe their own local heroes. Women are slightly more notable than men among people born after 1600, while before 1600 it is the other way around.
