Description: During data collection, in item 12, of the section Education Characteristics of persons aged and over, some interviewers understood that the question referred to the conclusion of a previously-attended course, whereas the proper information should be having finished at least the first grade of a previously attended course. That mistake led to a distortion of the population's level of schooling. The following vaiables were corrected: V3001, V3009A, V3010, V3011a, V3012, V3013, V3014 and VD3001.
Actions: Microdata files corrected and replaced. Inclusion of an update note on the page of access to the files together with the Technical Note with the description of the methodology adopted for the correction of data.
