Cohort of users who share the same user property


Forum|alt.badge.img+1

Hi,

I’m trying to create a cohort of users who share the same user property without having to specify the actual value of the user property.

For example - A user property may be a hashed value of a user’s address. I’d like to create a cohort of users who share the same address as at least one other user. 

Is this doable within Amplitude Cohorts ? Appreciate any help on this. 

Thank you

Create a segmentation chart, choose custom formula, then do the difference of uniques and propcount. You’ll need to group the event by the property that you want to count.

Interesting use case! I don’t think you can do this, without going through each property value individually (which I’m sure you don’t want to do).

Hi Timothy, Right. Segmentation gives me the table I’m looking for, but unfortunately, I can’t seem to translate that into a cohort. 

Thanks for looking into this - much appreciated.

perhaps you can download the segmentation table and upload it as as cohort? I know that’s a bit manual, but might be an OK workaround.

Yes, that could be a workaround. For our use-case, we need to know if the user has entered the cohort in closer to realtime, so it isn’t ideal

I don’t know if it helps, but you can create a chart that counts the difference between counts of unique property values and unique users. So monitoring that would tell you when your case occurs, but not for which user.

Thanks @timothy-permutable That may help. How would I create a chart like that ?
