Description: During the data collection, in item 12, of the section Characteristics of Education for persons aged 5 and over, some interviwers felt that the question intended to investigate the conclusion of a previously attended course, whereas the correct information refers to being approved in at least the first grade of a course previously attended. That mistake led to errors in the level of schooling of the population. Corrections were made in the variables: V3001, V3009A, V3010, V3011a, V3012, V3013, V3014 and VD3001. There was a failure in two editing rules in the software CANCEIS hich were not properly interpreted at the moment of data imputation. GThat way there were changes in some registers for variables V40403 and V40763.
Actions: The microdata files were amended and replaced and a note of update was included on the page of access to the files, together with the Technical Note that describes the methodology adopted for the correction of data.
