GHS-POP R2022A - GHS population grid multitemporal (1975-2030)

Collection: GHSL : Global Human Settlement Layer 

Description

The spatial raster dataset depicts the distribution of population, expressed as the number of people per cell. Residential population estimates between 1975 and 2020 in 5 years intervals and projections to 2025 and 2030 derived from CIESIN GPWv4.11 were disaggregated from census or administrative units to grid cells, informed by the distribution, density, and classification of built-up as mapped in the Global Human Settlement Layer (GHSL) global layer per corresponding epoch.

This dataset is an update of the product released in 2019. Major improvements are the following: use of improved built-up surface maps (GHS-BUILT-S R2022A); use of more recent and detailed population estimates derived from GPWv4.11 integrating both UN World Population Prospects 2019 country population data and World Urbanisation Prospects 2018 data on Cities; better representation of cities population time series; systematic improvement of census coastlines; systematic revision of census units declared as unpopulated; integration of non-residential built-up surface information (GHS-BUILT-S_NRES R2022A); spatial resolution of 100m Mollweide (and 3 arcseconds in WGS84); projections to 2030.

  • GHS population grid, derived from GPW4.11, for 1975-2030 (5yrs interval). Values are expressed as decimals (Float). The data is published at medium and low resolution (100m and 1km respectively) in World Mollweide (EPSG:54009). The grids in WGS84 (EPSG:4326) are produced from the 100m World Mollweide grids and have a spatial resolution of 3 arc-seconds and 30 arc-seconds.

  • Abstract

    Global population grids are increasingly used and required for countless applications in analysis, modeling, and policy-making. However, better and comparable global information requires improved geospatial data on population distribution and densities, in particular concerning temporal and spatial resolution and capacity for change assessment. This paper presents the development of improved global multi-temporal population grids, by combining best-available population estimates for 1975, 1990, 2000 and 2014, with best-available assessment of the spatial extents of human settlements as inferred from Landsat satellite data for same periods. Using a dasymetric mapping approach, population is disaggregated from finest census or administrative units to built-up areas. These 250-m grids represent population changes in time, having also higher spatial resolution than those previously available. The novel population grids constitute currently the de facto state-of-the-art in terms of open global geospatial population data, potentially enabling advances in many of the fields where this information is relevant.
