Products and services / Information / Microdata files

This page includes a list of statistics that can be used to obtain microdata files. Microdata files comprise individual data for one given statistic, which have been filtered appropriately to achieve anonymous information so as to ensure confidentiality. These ASCII files have a field-based structure and garner the values for each variable for each individual survey recording.

When using microdata files, any published information including data obtained thereby must quote the INE as the primary data source (source: INE, www.ine.es). Furthermore, the level of accuracy or reliability of the information derived drawn up by the authors is exclusively their responsibility.

To access a microdata file for a specific statistic, select the appropriate operation on this page. Another page will open showing the different periods available, ready for downloading, alongside all the information needed to understand the data: methodology, questionnaires, register design and relation of valid values for the data garnered in the survey.
