Adults by numeracy proficiency level . Level 5

Percentage of adults scoring equal to or higher than 376 points on the 0 to 500 point scale. Tasks at this level require the respondent to understand complex representations and abstract and formal mathematical and statistical ideas, possibly embedded in complex texts. Respondents may have to integrate multiple types of mathematical information where considerable translation or interpretation is required; draw inferences; develop or work with mathematical arguments or models; and justify, evaluate and critically reflect upon solutions or choices. The target population for the survey was the non-institutionalized population, aged 16-65 years, residing in the country at the time of data collection, irrespective of nationality, citizenship or language status. The proportion of adults scoring at different levels of proficiency adds up to 100% when the percentage of numeracy-related non-respondents are taken into account. Adults in the missing category were not able to provide enough background information to impute proficiency scores because of language difficulties, or learning or mental disabilities (literacy-related non-response).
