12 wrz 2022 · Based on the WorldPop dataset, we present a global gridded population dataset covering 248 countries or areas at 30 arc-seconds (approximately 1 km) spatial resolution with 5-year intervals for...
This interactive map shows population density in 2020, measured in residents per square kilometre. The data is from the Global Human Settlement Layer (GHSL) 2023 produced by the European Commission JRC and the Center for International Earth Science Information Network at Columbia University.
The Gridded Population of the World (GPW) collection, now in its fourth version (GPWv4), models the distribution of human population (counts and densities) on a continuous global raster surface.
The spatial distribution of population in 2020 with country total adjusted to match the corresponding UNPD estimate, China. Estimated total number of people per grid-cell. The dataset is available to download in Geotiff format at a resolution of 3 arc (approximately 100m at the equator).
19 kwi 2020 · Using this proposed method, we generated a set of 100-m SSPs population maps for China from 2015 to 2050 at 5-year intervals. Our projections revealed different spatial structures for the population distribution at the grid level and three modes of provincial population change across the five different SSPs from 2015 to 2050.
15 lip 2024 · Population is represented by maps of total, urban, rural population and population density as well as built-up area. The period covered is 10 000 BCE to 2023 CE. Spatial resolution is 5 arc minutes (approx. 85 km2 at the equator), the files are in ESRI ASCII grid format.
24 sty 2024 · There are two main methods for producing top-down gridded population data: area-weighted and dasymetric mapping, and bottom-up population mapping methods are adopted when census data is not...
