I think qatar is using "want to work" as a kind of shorthand. In the US I'm used to hearing about the unemployment rate. I don't know exactly how it's defined, but it only includes people who are sort-of looking for work: not full-time students or parents, retired people, independently wealthy loafers, or people with no-show sinecures.

Nice work extrapolating the various categories. I had to think a while to start seeing how one data point came from another. If you made a nice powerpoint showing how you reasoned this out, I bet you could get hired as a marketer, demographer, CIA analyst, etc.
