The Facebook Insights Audience report presents a demographic breakdown of fans who have liked the Facebook page being tracked. Specifically, the report enables you to access Page Fan demographic breakdowns according to age, gender, geolocation, and language.
Facebook indicates that their Insights metrics are only generated for Facebook Pages that have more than 100 people that like it. Likewise, demographic metrics, such as age, gender and location, are available in Page Insights once there is data for 100 or more people.
Important! In order to view this report, you must authorize a connection to a Facebook account that has Admin permissions for a Facebook Page.
Facebook limits the amount of data available via their API to 90 days. We follow Facebook's best practices in order to provide the reporting that they allow. We review third-party developer API changes monthly, so if they change the rules to allow for a longer reporting period, we'll update our reports accordingly.
