This paper presents the results of the analysis of the causes for duplicate profiles in the Scopus database on the basis of a random sampling of profiles of 400 Russian authors and 400 organizations. We estimate the number of duplicate profiles and calculate the level of uncertainty that errors in bibliographic descriptions can contribute to the results of scientometric studies using the Scopus database. The analysis showed that in Scopus 76% of the organizations and 24% of the authors have duplicate profiles. In this regard, organizations lose an average of 17% of publications and authors lose 11%. The results of this study can be used in elaboration of the Scopus database and estimating the error level in the research assessment of institutions and individuals.
