The Global Human Settlements Grid (GHS), produced by the European Commission Joint Research Centre (EC JRC), highlights areas with a dense population and a high degree of built-up land. It assesses the REGIO-OECD “degree of urbanization” model using as input the population grid cells in 4 epochs (2015, 2000, 1990, and 1975). Each km2 grid cell has been generated by integration of built-up areas produced from Landsat image and population data derived from the Center for International Earth Science Information Network Gridded Population of the World, Version 4 (CIESIN GPW v4). These data are divided into 3 discrete categories: urban centers, urban cluster, and rural areas. Urban centers, or high density clusters, are defined as “contiguous cells (4-connectivity, gap filling) with a density of at least 1,500 inhabitants/km² or a density of built-up greater than 50%, and a minimum of 50,000 inhabitants” per cluster. Urban clusters are lower-density clusters including towns and suburbs, defined as contiguous grid cells with a population of at least 300 inhabitants per km² or a density of built-up greater than 50% and a minimum of 5,000 inhabitants. Rural areas are defined as grid cells outside high-density clusters and urban clusters. Resource Watch shows only a subset of the data set.
