In Google analytics, there is a report category called "demographic". In this category, there are some reports about user, like age, gender and interest etc.
I am wondering could we implement the similar things in adobe analytics?
Actually, for stuff like this, I'd recommend Customer Attributes. Arun is correct though in that Adobe Analytics does not offer this data out-of-the-box.
Demographic details are not available in Adobe Analytics by default.
If you are capturing Customer Identification in Adobe Analytics, you can use Data Source to import the external data i.e. Demographic details from your external database.
