PIAAC › Public Data & Analysis
The data collection for the Survey of Adult Skills (PIAAC) took place from 1 August 2011 to 31 March 2012 in most participating countries. Around 166 000 adults, representing 724 million adults aged 16 to 65, were surveyed in 24 countries and sub-national regions in the official language/s of the countries.

The International Data Explorer (IDE) allows you to create statistical tables and charts to explore adults' (16-65 years of age) performance in literacy, numearcy, and problem solving in technology-rich environments. Data can be analysed by country as well as in relation to demographic characteristics, social and linguistic background, education, use of skills and employment status.
Public Use Files containing individual unit record data in SAS and SPSS format are available for downloading for each of the countries participating in the Survey of Adult Skills other than Australia. These contain both responses to the background questionnaire and the cognitive assessment. Full documentation of the contents of the files is provided. Please note that these files are primarily designed for use by researchers and data analysts. The files are also large and may take some time to download. To access the Australian Public Use File please write to: firstname.lastname@example.org
SAS® Macro (version 2.0). Please note that this file was updated on 18 December 2013; 27 March 2014 and 11 July 2014. (For any queries or to be informed of any update on this macro, please contact email@example.com).

Data compendia - Background variables. Please note that these files were updated on 13 November 2013.
Data Compendia - Cognitive variables.The compendia are sets of tables that provide categorical percentages for both cognitive and background items. The purpose of the compendia is to support PUF users so that they can gain knowledge of the contents of the PUF, and can use the compendia results to be sure that they are performing PUF analyses correctly. Note that due to the design of the cognitive assessment, comparisons of the cognitive item statistics provided in the compendia across countries for reporting purposes may not be appropriate.

International Adult Literacy Survey (IALS) and the Adult Literacy and Life Skills Survey (ALL)
Public use microdata files containing data from the International Adult Literacy Survey (IALS) and the Adult Literacy and Life Skills Survey (ALL) can be accessed from Statistics Canada using the following links.
These files contain results for literacy (IALS and ALL) and numeracy (ALL) on the same scales as the results from the Survey of Adult Skills (PIAAC). The process for linking results from the Survey of Adult Skills (PIAAC) and those from IALS and ALL is described in the Technical Report of the Survey of Adult Skills.
The International Database (IDB) Analyzer facilitates the analysis of data from the Survey of Adult Skills (PIAAC). It creates SPSS code that can be used with SPSS to conduct statistical analyses, taking into account the complex sample structure of the databases. The software allows you to combine data from different countries for cross-country analysis and to select specific subsets of variables. It provides several different procedures for analysis, such as the computation of means or percentages of any background variable of interest for a whole country or subgroup within a population.
