Rural population count at 1 km for 2000-2020 based on WorldPop and GHS-SMOD urbanization level

<p>Rural population count at 1 km grid in EPSG:4326 for 2000-2020 (annual). This is only an estimate of the rural population. This probably misses many rural areas, especially in the tropics. The maps were derived using two data sources:</p> <ol> <li><a href="https://hub.worldpop.org/geodata/listing?id=64">WorldPop population counts at 1 km</a>;</li> <li><a href="https://human-settlement.emergency.copernicus.eu/download.php?ds=smod">GHS-SMOD urbanization levels at 1 km</a>;</li> </ol> <p>Rural population is estimated using the following translation rules for GHS-SMOD (note: these are arbitrary rules based on the GHS-SMOD documentation):</p> <ul> <li>Class 30: &ldquo;Urban Centre grid cell&rdquo; = 0% rural</li> <li>Class 23: &ldquo;Dense Urban Cluster grid cell&rdquo; = 0.5% rural</li> <li>Class 22: &ldquo;Semi-dense Urban Cluster grid cell&rdquo; = 2% rural</li> <li>Class 21: &ldquo;Suburban or per-urban grid cell&rdquo; = 15% rural</li> <li>Class 13: &ldquo;Rural cluster grid cell&rdquo; = 95% rural</li> <li>Class 12: &ldquo;Low Density Rural grid cell&rdquo; = 100% rural</li> <li>Class 11: &ldquo;Very low density rural grid cell&rdquo; = 100% rural</li> </ul> <p>The nighttime images are based on: <a href="https://doi.org/10.5281/zenodo.7750174">https://doi.org/10.5281/zenodo.7750174</a></p> <ul> <li>Schiavina, Marcello; Melchiorri, Michele; Pesaresi, Martino (2023): GHS-SMOD R2023A - GHS settlement layers,<br>application of the Degree of Urbanisation methodology (stage I) to GHS-POP R2023A and GHS-BUILT-S R2023A,<br>multitemporal (1975-2030).
