How can gross school enrollment ratios be over 100 percent?
School enrollment, primary (% gross) is a gross measure and can be higher than 100. The same applies to gross enrollments for other levels of education. Gross enrollment ratio is the ratio of total enrollment, regardless of age, to the population of the age group that officially corresponds to the level of education shown. Primary education provides children with basic reading, writing, and mathematics skills along with an elementary understanding of such subjects as history, geography, natural science, social science, art, and music. “Gross” enrollment includes students of all ages. In other words, it includes students whose age exceeds the official age group (e.g. repeaters). Thus, if there is late enrollment, early enrollment, or repetition, the total enrollment can exceed the population of the age group that officially corresponds to the level of education. “Net” enrollment includes only children of the official school age, as defined by the national education system.
