Nauka 2/2022, 35-70.https://hdl.handle.net/10593/27044In this text, we analyze the limitations of using academic age as a proxy for biological age in the whole national science system, for which we consider both biological age and academic age of all researchers from all Polish universities, holding at least a PhD degree and participating in global academic science through international publications (N = 20 569). An approximation of a researcher's functioning in global science is having at least one publication indexed in the Scopus database in the analyzed decade 2009-2018. Thus, using the example of comprehensive data from the entire national system of science, we estimate the extent of limitations of using academic age as a proxy for biological age depending on selected independent variables and analyze both the practical and methodological implications of using academic age in academic career research, which is one of the most important components of quantitative studies of science.polinfo:eu-repo/semantics/openAccesswiek akademickiwiek biologicznynauki ścisłe a nauki humanistyczne i społecznepokolenia akademickiepublikacje indeksowane w bazie Scopuspolscy naukowcynauka w Polsceprofesja akademickakadra akademickamłodzi naukowcyArtykułhttps://doi.org/10.24425/nauka.2022.140330
