Track ongoing research productivity with the 2025 i10 Index Productivity Rankings.
By counting the number of publications with at least 10 citations, the i10 index highlights steady scholarly output and publishing consistency. These rankings offer insight into researchers’ contribution frequency, beyond cumulative impact. The system is regularly refreshed to reflect current performance trends, enabling up-to-date comparisons across fields, institutions, and regions. Premium access includes productivity heatmaps, time-based output trends, and in-depth author benchmarks.
