Territory size is proportional to the secondary school-age population (age 11 to 16) attending secondary education in the period 2010-1015.
This map uses data from the 2016 United Nations Human Development Report and population estimates from the 2017 World Population Prospects (last accessed March 2018). We aim to map as complete data as possible and therefore estimate data for missing values. In some cases, missing data for very small territories is not used in the cartogram and that area is therefore omitted in the map.
Further notes on the data, as well as all modifications to the original data source are noted in our data sheets. Data for this map will soon be available as a download.Download data file
