OECD Skills Studies Survey of Adults Skills 2023 Data AnalysisManual Foreword The Survey of Adult Skills, a product of the Programme for the International Assessment of Adult Skills(PIAAC), is a household survey designed to collect information on the skills proficiency of the adultpopulation aged 16-65. The purpose of this Data Analysis Manual is to guide researchers and users who are interested in analysingthe microdata collected in the 31 countries that participated in the second cycle of the survey in 2022/2023. Adults who participated in the survey were randomly selected toform a representative sample of theunderlying population. They answered a background questionnaire (administered by trained interviewers)and then completed a direct assessment of literacy, numeracy and adaptive problem solving. Adults whowere unable tocomplete the normal background questionnaire and the assessment due to languagebarriers were administered a shorter questionnaire (called “doorstep interview”), available in multiplelanguages, that they could self-complete on a tablet. Part I of this manual provides a brief overview of the different datasets related to or derived from the Surveyof Adult Skills, provides guidance on how they can be accessed, and describes in some details their contentand all the information collected through the survey. Part II focuses instead on how the data should be analysed. It describes how to appropriately conductstatistical analysis, in particular how to take into account the complex survey design used during datacollection and how to derive correct inferences when working with the measures of skills proficiencycontained in the PIAAC datasets. Available tools to facilitate the analysis of PIAAC data are also presented. This Data Analysis Manual complements two other PIAAC products: the Reader’s Companion(OECD,2024[1])and the Technical Report(OECD, forthcoming[2]). The Reader’s Companion offers a broad andless technical overview of all aspects of the Survey of Adult Skills with the aim to help readers understandand interpret the results of the survey. While it is intended for the general public, many data users andresearchers will find the Reader’s Companion a useful reading to familiarise themselves with PIAAC andbetter gauge the analy
