Total number of literate persons in a given age group, expressed as a percentage of the total population in that age group. The adult literacy rate measures literacy among persons aged 15 years and above, and the youth literacy rate measures literacy among persons aged 15 to 24 years.
Some of the learners can be expected to have had some primary schooling. The actual proportions are likely to correlate with the literacy rate of the country: countries with high literacy rates are likely to have high proportions of primary school dropouts who wish to capitalize on opportunities for a ‘second chance education’. In multilingual countries, instruction in the dominant official language is likely to increase the participation of primary school dropouts (Oxenham, 2008: 48).
