It's not to say it hasn't been done, but I haven't seen those demographics. I will check, and if we have them I'd be happy to file them with the committee.
We do public polling every year, and this year we ran a survey, hired a company called the Quorus Consulting Group, that ran what we call the “consumer attitudes on mobile giving”. To the question earlier of whether we're eating the lunch of existing charities, importantly 87% of donors who used this mobile platform did so in addition to donations they made through traditional means.
In terms of age or income, if we have that information I'll file it with the clerk. But we do poll our users regularly.
