Recently someone in a local Facebook group asked members to post their ages. In the twelve or so hours since that posting, these are the ages of the people playing Pokemon Go and who are members of the group and who responded (a selective non-representative sample, for sure). Here are the results, grouped unscientifically. They wouldn't be much different with other groupings.
Total number responding:
- Under 20: 6
- 20-25: 34
- 26-30: 23
- over 30: 11
As it was easy to observe while out in the parks, meeting the Pokemon Go players, the bulk of them are in their 20s. But I also met many others who are older (none as old as I am) but who are likely not members of the local Facebook group and/or who aren't willing to post their age. [I listed mine as "under 90" of course; see this].
I've been having fun, catching Pokemon, meeting new people, getting exercise. Ms Eclectic would say it's an obsession now, if not an addiction for me. I expect it all to fade, though.
