Hi, Just to add to this, here is a link to a document I made with the sort of data you suggested sharing in the conversation earlier this year about cohort data. (Some of this is already contained in the Giving Review but I’ve presented it by cohort to hopefully make it easy to read). I agree that it’s useful to collect and share, so thank you for the prompt!
This is impressive—several thousand dollars of donation per member, with no obvious trend downwards excluding the first cohort (which was filled with especially large givers). This easily suggests a member is worth tens of thousands of dollars of donations.
And I’d expect My Giving data to underreport, since there will be people who donate but don’t both to fill it in.
Hi again! I’ve now had a look at this—for the cohorts who joined before 2013 it looks like 30% of those who reported meeting their pledge in 2014 had not reported meeting their pledge in 2013. So this shows that just because someone didn’t report their donations in 2013 doesn’t mean they didn’t the following year. I have added a breakdown of this in the 2014 cohort document. (NB I also made some very small corrections to the 2013 cohort info, which slightly increased the numbers for ‘people who recorded some income and donation data’ and changed the median %’s donated)

Thanks Allison for such a clear document!
Do you have similar numbers for the 2013 pledge?
Hi Peter, I don’t yet but am working on it: I’ll post them here when they’re done :)
Thanks! :D
Here is the cohort information for 2013
Do you know what the overlap is like? Are the people going silent in 2013 the same people who go silent in 2014?
Thanks!
