The table below shows the latest figures for numbers of Cochrane Members and Supporters, listed by country. Numbers are updated each quarter and archived by year.

  • Cochrane Members - Cochrane’s core contributors who have earned membership
  • Cochrane Supporters - our global community of Cochrane Account holders who are actively engaged (have logged in to their account within the last 2 years) 

Why have the member and supporter numbers in my country changed? People may have relocated and changed their country of residence; people’s level of engagement with Cochrane may have changed.
Why is there no historic data for members and supporters in my country? Data will be shown from the moment that someone signs up in a geographic area, or changes their country of residence. We welcome new members from around the world all the time. There are now Cochrane Account holders in nearly every country across the globe!

More detailed information about contributor activity is published annually:
Cochrane Geographic Group annual activity reports.
