I don't have those numbers. I would point out that of the work that's been done about benefits that people are missing out on.... The PBO says it's two billion; academic studies say it's 10% to 12% of people. Those are not up-to-date numbers, and they're not detailed, so it's hard to know exactly how many. I'm relying on information from talking to people and to civil society groups that are working with those people on the front lines. To add up a big macro number is very hard. I would really like to know.
There's a whole other area of research to be done, too, in terms of indigenous populations and reluctance to file tax forms because of a trust bond or for various reasons. We don't know—we don't thoroughly understand—what that dynamic is.
