We do not have enough age data from our members as we only recently started collecting. But we know there are significant outliers though in the member base. A lot of them are indeed in the typical 25 to 34 year old age group. But we have a lot of "empty nesters" who when their kids left the house decided to sell everything and travel perpetually. And we can only see this group growing in the future. Also the 35 to 44 year olds group will be growing since the digital nomads that started out 10 years ago as 25 year olds, are now reaching this age group. Many of them settle down in multiple places, but also many of them keep traveling like nomads, perhaps slowing down.

Especially in this scene, age seems to be much less important than people's mindset and at what stage they are in their life. Are they traveling while studying (on hold)? Are they working on a remote career? Building a business? Retired? Not many really care about your age.
