Out-of-school rate for adolescents of lower secondary school age, both sexes (household survey data) (%)

Number of children of official lower secondary school age who did not attend primary or secondary school at any time during the reference academic year, expressed as a percentage of the number of official lower secondary school age children in the household survey sample. Children attending pre-primary or non-formal education are considered out of school. The UNESCO Institute for Statistics (UIS) releases estimates of out-of-school children calculated from both administrative and household survey sources (Demographic and Health Surveys and Multiple Indicator Cluster Surveys). Administrative records and household surveys are two data sources which differ in fundamental ways: who collects the data, as well as how, when and for what purpose. As a result, the out-of-school children estimates calculated from one data source may not match those based on other data sources.
