Hi,
I would be very interested to know if it would be possible to find out an economic statistic indicating how much of the economy is being supported by initial purchases by new residents who buy things, but then leave.
For example, we have the "users logged in in past 30 days" statistic. It would be interesting to find out how many of the transactions in the period from 60 days in the past to 30 days in the past were made by users who did not log in in the past 30 days.
