A ratio of the number of pupils or students in a given age group (as of the beginning of the school year) at a given level of education to the population (as of 31 December) in the age group defined as corresponding to this level of education.

Net enrollment rate, e.g. for the primary school level, is calculated by dividing the number of primary school students aged 7-14 (age assigned to this level) at the beginning of the school year by the population aged 7-14 years, as of 31 December of the same year; the result is given in percentage terms.
