How is this information collected? When I was looking for work after grad school I didn't report to anyone as such. The school had no idea whether or not I was actively looking. I was denied unemployment. I'm not sure what my info might have looked like on the IRS end if that is what is being abrogated.

It also specifically says unemployment figures isn't solely from state unemployment insurance figures.
