This is an update of HYDE, which is an internally consistent combination of historical population estimates and time-dependent land use allocation algorithms for 10 000 BCE–2015 CE. Categories include cropland, separated into irrigated and rain-fed rice and non-rice crops. Grazing lands are divided into more intensely used pasture and less intensively used rangelands. Population includes total, urban, and rural population and population density and built-up area.
