Adults from less educated families report, on average, lower openness to experience
The results of the 2023 Survey of Adults Skills confirm that parental educational attainment influences social and emotional skills well into adulthood (Figure 4.6). The analysis compares two groups of adults: those who have at least one parent who has attained tertiary education (adults with highly educated parents) with those whose parents have attained upper secondary education at most (adults with lower-educated parents). The results indicate that adults with highly educated parents demonstrate, on average, higher levels of openness to experience across all participating countries and economies. Similar differences are observed for extraversion in all countries and economies, except Canada, Chile, Czechia,
Italy, New Zealand and Portugal, where no significant differences are observed. In 12 countries and economies, emotional stability is also positively related to parental education.
Different patterns emerge for the Big Five domains conscientiousness and agreeableness.
In most countries and economies, adults with lower-educated parents report, on average, higher levels of conscientiousness than those with highly educated parents. Exceptions are Chile, Croatia, Estonia, Finland, Italy, Israel, Poland and the Slovak Republic, where the difference is not significant, and Lithuania, where adults from advantaged backgrounds report higher average levels of conscientiousness.
In Canada, England (United Kingdom), France, Ireland, Korea and Norway, adults with lower-educated parents score, on average, somewhat higher in agreeableness then adults with highly educated parents. In the remaining countries and economies, there is no significant difference between the groups, while in Austria and the Flemish Region (Belgium), the reversed pattern is observed.
