The population density category (SWECO25 v1.0.0) contains the "statpop" dataset. The statpop dataset describes the population density in Switzerland. Using the “Population and Households Statistics” (STAPOP) data points (FSO, 2020), we generated yearly raster layers for the 2010-2020 period. For each year, we computed 13 focal statistics layers by applying a cell-level function calculating the mean and the total (sum) number of inhabitants in a circular moving window of 13 radii ranging from 25m to 5km. This dataset includes a total of 297 layers. As requested by the FSO, for privacy concerns, pixels with 1 to 4 inhabitants were given a value of 4. Final values were rounded and multiplied by 100. This dataset includes a total of 297 layers. The detailed list of layers available is provided in SWECO25_datalayers_details_pop.csv and includes information on the category, dataset, variable name (long), variable name (short), period, sub-period, start year, end year, attribute, radii, unit, and path.
