If your report or exploration is missing data, it may be because Google Analytics has applied a data threshold.
Data thresholds are system defined, and you can't adjust them.
Thresholds are applied to prevent anyone viewing a report or exploration technique from inferring the identity of individual users based on demographics, interests, or other signals present in the data.
You may see thresholds applied under the following conditions:
If a report or exploration includes demographic information, such as Age, Gender, or Interest Category, and the reporting identity relies on the device ID, the row containing that data may be withheld if there aren't enough total users to prevent individual users from being identified.
For example, if there are fewer than N users of Gender=male in a report, then data for the male value may be withheld.
If your property collects data using Google Signals, then thresholding can be applied to any of the data rows.
If a threshold has been applied to a report or exploration, you will see the data indicator change color. You can hover over the indicator to see more information. (The data indicator also shows whether sampling has been applied.)
