Since its establishment, the AD Scientific Index has expanded in terms of the number of countries, institutions, and scientists as follows:
- May 25, 2021: 417,605 scientists, 167 countries, 9,525 universities
- June 18, 2021: 700,093 scientists, 182 countries, 11,350 universities
- June 5, 2022: 948,737 scientists, 216 countries, 15,652 universities
- October 1, 2022: 1,082,054 scientists, 19,490 universities
- April 1, 2023: 1,350,571 scientists, 218 countries, 21,500 universities
- September 12, 2024: 2,399,177 scientists, 219 countries, 24,21 institutions
The AD Scientific Index is continuously growing and currently includes 2,400,165 scientists, 24,296 institutions, and 219 countries. While the list is regularly expanded, new additions are limited to individual and institutional registrations to ensure data accuracy and reliability. Please note that requests made via email or other communication channels are not considered; the only way to be included is by completing either an individual or institutional registration through the 'Register' link on our website.
We do not have a policy of automatically including every profile in the system. This approach is necessary to manage the ongoing effort required to ensure the accuracy, integrity, and validity of data at both the institutional level (e.g., mergers, splits, name changes, closures, license revocations, and suspensions) and the individual level (e.g., institutional changes, profile deletions, deaths, ethical violations, and other updates).
Many profiles have been removed for various methodological reasons, and in some cases, individuals have requested to be removed from the list. Additionally, we would like to remind you that our methodology has brought to light many ethical violations and rule-breaking behaviors, which have been reported by institutions and other individuals, and those profiles have been removed accordingly.
