For most websites I am familiar with, 20-30% of users use adblockers or other privacy plugins. On content with a target audience of developers I have sometimes seen 60%. Most of these users are not recorded in google analytics, so the real number of unique users is higher than reportet by analytics. Since no data from these users is sent at all (no user data and no pageview data) page views per user is not directly influenced because your are missing users and pageviews in your reporting. It could be influenced because users with an adblocker behave differently then users without. To analyse this you would have to look at your server generated web logs. The given data in the image is often not used to find out what the total amount of unique users on your webpage is. It is used for computing engagement: Monthly active users vs. daily active users. In this example we only have 7-day active users and no daily active users, but it basically is like: 34738/107942=0.32. At a value of 1 (the maximum) you have a high engagement. In simple terms: Each user would come back every week for this month. 0.32 is quite low. Around 0.25 would be the lower bound because we have 4 weeks in a month.
