Notas:
Con fecha 18 de Marzo se han corregido los datos de esta tabla
Due to the lack of representativeness, estimates of the cells without data cannot be provided (to points)
The categories ¿Large Group 0¿ (Armed forces) and ¿No data recorded¿ are included in ¿Other case¿.
As of 2012, the new Classification of Occupations (CNO 2011) was incorporated, hence there will be categories that are not comparable with previous years where the classification CNO-94 was used. 
Households with employed main breadwinner.
