Credit card issuers don't release a lot of information about their cardmember demographic as they prefer to keep that information to themselves. Some people will be interested in what Monkey Miles has found.
The magazine for Amex Platinum card members is Departures. The publication has a media kit for potential advertisers, which includes demographic information about the readers. I think it's safe to assume that the magazine is intended to reflect the demographic of Amex Platinum cardmember.
The average Departures reader is an Amex Platinum cardmember.
There is also a magazine for Amex Centurion card members. The card is often referred to as the Black Card and invitation-only.
According to this, the average cardmember is a Centurion reader.
The numbers are from a magazine for cardmembers, not from Amex directly. It is possible that this comes from reader surveys. People will find these numbers interesting.
There are a few thoughts based on these numbers.
The media kit for the exclusive magazines for Amex Platinum and Centurion card members contains information about readers. Net worth, income, age, and properties are included.
I would have expected cardmembers to be older, richer, and have more properties, but these numbers surprised me.
What do you think about the Amex cardmember demographic?
