Notas:
Due to a lack of representativeness, estimates cannot be provided for the cells without data (to points)
"Large Group 0 (Armed Forces) categories and "No data recorded" are included in "Another case"
The new National Classification of Occupations (NCO-2011) has been included as of 2012, and therefore, there will be categories that are not comparable with previous years, in which the classification used was NCO-94.
