Does this explain why the number has not gone above 5 million, while the number of tax filers has increased? My sense is that some groups come before us and say that the number of people giving is not going up with the number of tax filers, so therefore we need things like the stretch tax credit to encourage people, especially middle- or lower-income people, maybe, or younger people, to give more. They say we need the stretch tax credit because of this information, so I want to make sure that I understand why this number is fairly constant.
