# Audience as a cube dimension

You can use an audience as a dimension in audience workbook cubes. This allows you to further analyse an existing audience workbook cube by switching out a dimension to use an audience as a dimension ‘on-the-fly’.

> [!NOTE]
>
> **Example use case**
>
> You could modify an existing audience with dimensions like region and gender by replacing the gender dimension with an audience representing people who have responded to a campaign.
>
> This new audience dimension provides a breakdown of people who have or haven't responded to your campaign, enabling deeper analysis of your original audience and offering additional insight into your respondents.
