[Analyze] Why isn't Twitter data available in the Audience tab?
The Audience tab displays information on your audience demographics, such as age and gender. This allows you to learn more about the people that matter to your business, and in turn, create content most suited to them.
Unfortunately, we are not able to provide this kind of data for Twitter profiles at the moment. Although audience data is available when viewing native Twitter Analytics, this data is not made available through Gnip, which is Twitter's enterprise data service that we use. Therefore, the data available within the Audience tab is limited to Facebook and Instagram. We really apologize for any inconvenience there.
