Similar correlation values were obtained by calculating the correlations for papers published in a specific year. By analyzing the number of new authors each year, we discovered a sharp increase over time, with several million new authors publishing each year in recent years see Fig. For example, researchers who started their careers in published on average 1. Furthermore, we observed that authors who started their careers after tended to publish more in conferences in the first years of their career than their more senior peers who started their careers in the s or s see Fig.

We can also observe that the mean number of co-authors has considerably increased over the decades Fig. Mean number of co-authors by academic birth decade. The mean number of co-authors has considerably increased over the decades. Additionally, with seniority, the percentage of published papers with the researcher listed as the first author decreased Fig. Moreover, by looking at the decade researchers started their careers, we can see a sharp decline in the percentages of first authors Fig. Overall, early-career researchers are publishing more in their careers but appear as first authors much less than in previous generations.

Percentage of times researcher was first author. We can observe that over time on average the percentage of senior researchers as first authors declined. Moreover, in the same time intervals, the percentage of times recent generations of researchers were first authors declined compared to older generations. By analyzing journal trends using the SJR and MAG datasets, we discovered that the number of journals increased greatly over the years, with 20, active ranked journals in Fig. In addition, we discovered that the number of published papers per journal increased sharply, from a mean of We also observed that in recent years, journals that publish thousands of papers have become more common.
