Unemployment rates are severely under tracked.

Unemployment rate just shows the % of people who do not have a job and are looking for a job.  Does not count the people who are not looking.

Should show:
the % of people that have a job
the % of people who are retired
the % of people who are under the age of majority

100% - the above 3 things = the true unemployment number

this pretty much sums up how they work out the figure.

there are are few other things, that very form country to country, like if they worked part of that financial year, they are not considered unemployeed
