How does Data Suppression work in SAS 8.2?

I’m trying to understand the way suppression works in SAS version 8.2. If I have a data set like

Students Gender

1 Male

7 Female

8 Total

And a business role to not show genders less than five will only the 1 for male be masked or will both male and female be masked with the total remaining?

As I understand it only the Male category would be masked. But as you can see you can still derive what the Male count is anyway. Your example would make more sense if the measure you were suppressing was a continuous number say something like grade variance which can't be derived.

Students Grade Variance Gender

* * Male

16 2.3 Female

20 2.5 Total

The suppression feature isn't just a straightforward filter that says If xxx is less then xxx then mask. It is more complex.

This community article provides an example of how the feature works.
