Since 2014 (Figure 6), SP has been receiving a growing number of
accreditations requests to access microdata and additional requests of
information. The advertising SP has been doing in universities and research
centres are the main reason for that, particularly about the possibility of easy,
free and fast access (three keywords) to statistical microdata for scientific
research purposes, which contributes to increase the satisfaction levels of the
national scientific community.
Meanwhile, SP has prepared files with information at observation unit
level, the so-called Public Use Files (PUFs).
These files (data and metadata) contain anonymised records, processed
and prepared in a way that the observation unit cannot be identified directly
or indirectly, with the exception of statistical data on Public Administration.
Accesses to these files are free and comply with the principle of statistical
confidentiality and personal data protection.
This offer helps to increase the interest and use of statistical data, mainly
for university, or even high school, students. The present offers of PUFs are:
• Census 2001 and 2011 (5% sample on individuals and dwellings).
The file corresponds to a 5% sample of residents. It includes two sampling
tables, one for family and collective dwellings, containing some variables
on the building; another table for resident individuals, both with 5%
registers and a common bonding variable.
• Public Museums, from 2013 to 2016.
The file contains annual data characterizing Museums, specifically, human
and financial resources, store, collections and inventory, visitors’ oriented
activities, number of visitors (monthly and annual flows), and type of
visitors (school groups and foreign visitors).
