I have always been bothered by the employment number. Or more precisely – the unemployment number.
I have always known that the unemployment, or employment, number is not related to the total population. Which made things more bothersome. While the total population is not mentioned along with the employment / unemployment number (which makes sense), but the number that should be available along with the unemployment number – the total employable population, is never available. When I did try to find this number – not only was it not easy to find, there seems to be different number for this at different sources. They all seem to use their own criteria of who should be in the pool of employable population.
But before I even begin to look into the various disparity in this definition, it seemed to me that we could never really know the number of people who are voluntarily and constantly leave or join the job market.
