Description
This dataset contains the Global Degree of Urbanisation Classification of administrative units delineated by the Global ADMinistrative layer version 3.6 (GADM36) according to the application of stage II of the Degree of Urbanisation. The classification is based on the Global Human Settlement Layer (GHSL) global datasets GHS R2022: the settlement classification GHS-SMOD (GHS-SMOD_GLOBE_R2022A), population grid GHS-POP (GHS-POP_GLOBE_R2022A), and built-up surface GHS-BUILT-S (GHS-BUILT-S_GLOBE_R2022A) layers for target years 1975-2030 (5 years timestep). This dataset contains a package composed by one excel table, a summary table gathering global summary statistics and by countries and territories in GADM3.6, and 72 CSV files, one per GADM level (from 0 to 5) and epoch (1975-2030), with all administrative units classified according to the Degree of Urbanisation. The spatial delineation of GADM 3.6 administrative units is available at GADM official website (accessible through the link below). Please select the whole world shapefile as six separate layers (one for each level of subdivision/aggregation). The vector layers can be used to join each classification table (csv) with the actual spatial units.

Abstract
The Degree of Urbanisation is a new definition of cities, towns and semi-dense areas, and rural areas endorsed by the UN Statistical Commission. The urban population share according to the Degree of Urbanisation is similar to the one based on national definitions in the Americas,Europe and Oceania, but considerably higher in Africa and Asia. An empirical analysis and a comparison of concepts suggest that towns are likely to be classified as rural areas in Africa and Asia and as urban areas in other parts of the world. The paper shows that cities cover only a small share of land, but this share doubled over the past forty years, as has the number of cities. Although cities have expanded rapidly, their population grew even faster leading to higher densities. The paper tests two classic urban facts: 1) the cities and towns as defined by the Degree of Urbanisation closely follow Zipf’s law 2) the population shares in urban areas, cities and especially metropolitan areas are positively and significantly correlated with the level of economic development. Lastly, the sensitivity of the classification of population and land are tested by varying the population size and density thresholds as well using a different global population grid.
