Except that we don't track those numbers, so it could be that earlier in the recession more people were recently out of work, and looking hard, meaning they were counted in this number. Right now, it's been a lot longer, so perhaps many of them have given up, even if they need jobs, so they are no longer being counted.
The number of people needing jobs, regardless of searching might have gone down similarly to the reported number, or it might have stayed exactly the same overall. Without the information, we don't know. I certainly know a few people who need jobs and can't get them, and some of them aren't being counted. Maybe it would be good to find out.
