In a dynamically developing scientifi c environment, there is a tendency toward creating mechanisms that objectively evaluate the output of individual scientifi c units. Selected indicators can be applied, inter alia, to work out specifi c criteria for awarding funds for scientifi c research activities. One of the most important indicators used is the impact of researchers' publications, which today determines the overall outcome of the evaluation of a research unit. Th e key question in this context is whether any socio-demographic factors are correlated with the impact of the scholarship work of individual researchers and, if yes, what those indicators are, specifi cally. Th e purpose of this study was to determine the existence and, if confi rmed, the nature of correlation between the impact of researchers' publications and selected socio-demographic factors such as: age, gender and family status. Th e study sample included all the academic employees of the Faculty of Political Sciences and International Studies, Nicolaus Copernicus University, in Toruń (Poland). Th e results demonstrated that the socio-demographic factors considered showed little correlation with publications' impactfulness as measured in the Polish evaluation system of research units.
