Percentage of adults scoring 176 to less than 226 points on the 0 to 500 point scale. Tasks at this level require the respondent to carry out basic mathematical processes in common, concrete contexts where the mathematical content is explicit with little text and minimal distractors. Tasks usually require one-step or simple processes involving counting, sorting, performing basic arithmetic operations, understanding simple percents such as 50%, and locating and identifying elements of simple or common graphical or spatial representations. 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).
