In an effort to develop a clearer picture of the distribution of skills demanded by modern societies, the Organisation for Economic Co-operation and Development (OECD) undertook the Programme for the International Assessment of Adult Competencies (PIAAC), a new survey of adult skills. Unlike school-based surveys, which focus on specific ages or grades of in-school students, PIAAC was designed as a household study of nationally representative samples of adults age 16 to 65. This report disaggregates the PIAAC data for millennials—the cohort born after 1980. Key findings are summarized below and detailed supporting data can be found in the full report. All differences noted are statistically significant.
