Gridded population estimates for Ukraine using UN COD-PS estimates 2020, version 2.0

This README file provides information about the data included in the data release, how it was produced, source data that were used.

This geotiff raster, at a spatial resolution of 3 arc-seconds (approximately 100m at the equator), contains estimates of total population size per grid cell across Ukraine. NA values represent areas that were mapped as unsettled based on the DLR settlement layer]. These data are stored as floating-point numbers rather than integers to avoid rounding errors in aggregated populations for larger areas.

This zip file contains 34 raster files in geotiff format at a spatial resolution of 3 arc-seconds (approximately 100m at the equator). Each raster provides gridded population estimates for an age-sex group of settled areas (NA represent unsettled areas). Files are labelled with either an “M” (male) or an “F” (female) followed by the age-range of the group (five year bins). For instance, “F_00_04” and “M_05_09” are population counts of under 5 year olds for females and between 5 and 9 years old for males, respectively. Eighty year olds and over are represented in the groups “F_80Plus” and “M_80Plus”. These data were produced using age-sex national proportions from COD-PS. The age-sex proportions were applied to the gridded population estimates (ukr_pop_2020_100m_constrained_v2) to allocate the population to the different age-sex classes. While this data represents population counts, values contain decimals, i.e. fractions of people. This is because we do not estimate which grid cell each individual in a given age group occupies. For this reason, it is advised to aggregate the rasters at a coarser scale. For example, if four grid cells next to each other have values of 0.25 this indicates that there is 1 person of that age group somewhere in those four grid cells.

This zip file contains 3 rasters in geotiff format at a spatial resolution of 3 arc-seconds (approximately 100m at the equator). Each raster provides gridded population estimates for children-age (0 to 18 years old) of settled areas (NA represent unsettled areas). Files are labelled with either an “M” (male) or an “F” (female) or “F_M” for both male and female. These data were created by applying the Sprague multipliers to “ukr_agesex_2020_100m_constrained_v2 “ raster data. Sprague multipliers are used to interpolate data and obtain population estimates by single years of age and these are then aggregated to 0 to 18 years of age.

This geotiff raster, at a spatial resolution of 30 arc-seconds (approximately 1km at the equator), contains estimates of total population size per grid cell across Ukraine. NA values represent areas that were mapped as unsettled based on the DLR settlement layer. The dataset was produced by aggregating the ukr_pop_2020_100m_constrained_v2.tif dataset to 1km.

Each raster provides gridded population estimates for an age-sex group of settled areas (NA represent unsettled areas). These datasets were produced by aggregating the ukr_agesex_2020_100m_constrained_v2 datasets respectively to 1km.
