# Audience data reference

Find the audience data available when configuring audiences for messages and experiments.

Airship evaluates your audience at the channel level or contact level, depending on when your project's account was created and whether it has migrated to contact-level segmentation. For explanations of each system, see [Segmenting your audience](https://www.airship.com/docs/guides/audience/segmentation/about/).

## Contact-level segmentation

The following audience data is available in the contact-level segmentation system.
