When you define a user segment, you are defining a target audience. Self Service uses user segments to:
- Set field security on global fields 
- Set list value security on list field values 
- Set value security on the intrinsic fields Owning Group, Internal Audience, and External Audiences 
- Identify targeted content displayed on Self Service sites 
For information on creating user segments, refer to the ATG Business Control Center Administration and Development Guide.
Note: Anonymous users default to “female.” When creating a segment that looks for female users, anonymous users will be included in the segment.
