Hi! I am on this topic, too: I am reporting New and Returning Visitors in Google Data Studio and they don’t sum up to total. Do you have any explanation or hint on that? ![image](https://europe1.discourse-cdn.com/flex005/uploads/piwikpro/original/1X/943a6f537bc0f4a6f86e08597fc099341580a780.png) Thanks, Susanne ---

Hi @Susanne, this metric is based on visitors’ sessions. Keep in mind that each returning visitor (unique visitor id) started the journey being a new one. So the sum won’t equal the total. ---

ok thanks, I understand. It is similar to Google Analytics.
