A proportional allocation gridding algorithm, utilizing approximately 12.5 million national and sub-national administrative units, is used to assign population values to 30 arc-second (~1 km) grid cells. The population density grids are derived by dividing the population count grids by the land area grids. The pixel values represent persons per square kilometer.", "distribution": [{"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C3540917665-ESDIS.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://beta.sedac.ciesin.columbia.edu/data/set/gpw-v4-population-density/docs", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.7927/H4NP22DQ", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C3540917665-ESDIS", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.7927/H4NP22DQ", "keyword": ["earth-science-population-human-dimensions-population-density"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-23", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ESDIS"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -180.0, \"NorthBoundingCoordinate\": 85.0, \"EastBoundingCoordinate\": 180.0, \"SouthBoundingCoordinate\": -60.0}]]", "temporal": "2000-07-01/2005-07-01", "theme": ["Earth Science"], "title": "Gridded Population of the World, Version 4 (GPWv4): Population Density"}
