Gridded population estimates for Turkey using UN COD-PS estimates 2021, version 1.0

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 Turkey. These results were produced using subnational population estimates for Turkey in 2021 provided in the Common Operational Dataset on Population Statistics ( COD-PS). NA values represent areas that were mapped as unsettled based on the GHS settlement layer . These data are stored as floating-point numbers rather than integers to avoid rounding errors in aggregated populations for larger areas.

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 Turkey. NA values represent areas that were mapped as water. These data are stored as floating-point numbers rather than integers to avoid rounding errors in aggregated populations for larger areas.

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 Turkey. NA values represent areas that were mapped as unsettled based on the GHS settlement layer. The dataset was produced by aggregating tur_pop_2021_100m_constrained_v1.tif dataset to 1km.

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 Turkey. NA values represent areas that were mapped as water. The dataset was produced by aggregating tur_pop_2021_100m_unconstrained_v1_0.tif dataset to 1km.

This zip file contains 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 surface waters). 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 (tur_pop_2021_100m_uconstrained_v1) 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.
