Abstract: In this article, we undertake a comprehensive large-scale analysis of the evolution of scientific communities across different disciplines and countries, spanning the period 1991-2020. Our analysis uses data obtained from Scopus and involves a total of 15,756,144 authors, 74,847,508 publications, and 1,501,206,153 citations. Besides the overall research production, we investigate multiple disciplines at various levels of aggregation (namely, scientific sectors as defined by the European Research Council and Scopus research categories). The geographical focus of our analysis takes into account first the worldwide scientific production and then addresses the 19 countries that are members of the G20 group (thus excluding the EU).
