Thanks for your reply. Read post #2 then explain how unemployment goes down. That was my question.
Likely I said, the numbers count job seekers. If you reduce the count of jobs seekers at your local workforce boards, you reduce unemployment. This is the field in which I work.
And as autumnraine posted, there are interviews conducted.
