Norway has one of the highest public employment rates (as a fraction of the total employment) in the "developed world" (around 30%, the highest in the OECD32 and about twice the average of the OECD32, as of 2008).
However, Norway total public spending (as a percentage of the total GDP) is low (or moderate) and much lower than those ones from countries with high public employment rates (Denmark, Sweden, Finland, and France). I would guess that expenditure in public jobs is a big fraction of the total government spending, together with pensions. And this seems to be confirmed to some extent by the two previous charts, at least for those countries with the highest public employment: Denmark, Sweden, Finland, and France have high public spending (greater than 55%) and high public employment rates (greater than 20%). However, Norway seems to be one exception. Why is that? Is because the fraction of high-qualified public workers (doctors, professors, teachers -- those who have a higher income) is not as high as in France, Sweden, Denmark, and Finland?
Below you can see a chart with the public spending segmented in categories. Is the reason that most public jobs are usually in education and health, and Norway public spending in these sectors is as high as in Sweden, Finland, Denmark, or France? Os is it due to something else?
