The percentage of the population (age 25 and over) with unknown educational attainment. This indicator is calculated by dividing the number of persons aged 25 years and above with unknown educational attainment by the total population of the same age group and multiplying the result by 100. The UNESCO Institute for Statistics (UIS) educational attainment dataset shows the educational composition of the population aged 25 years and above and hence the stock and quality of human capital within a country. The dataset also reflects the structure and performance of the education system and its accumulated impact on human capital formation.
