Esri and WorldPop Partner to Provide Updated Demographics to Decision Makers


REDLANDS, Calif .– (COMMERCIAL THREAD) – The world’s population has grown by almost two billion people over the past 20 years, or nearly 30%. Such growth is not evenly distributed over time or space: extremes include Qatar which increases by 400% and Lithuania which loses 25%. And even within countries, the growth rate varies. To meet the need for up-to-date demographics that reflect these changes, WorldPop and Esri, the global leader in location intelligence, have teamed up to include WorldPop’s 1km annual gridded demographic datasets in ArcGIS Living Atlas of the World. The data cover 241 countries, territories and dependencies for the period 2000-2020.

“These datasets are essential for measuring and monitoring the socio-demographic changes that accompany them over time and for properly informing and supporting environmental, health and development applications at local, sub-national, national and regional levels,” said Professor Andrew Tatem, Director of WorldPop at the University. from Southampton. “In this context, comparable, multitemporal and spatially explicit detailed population distribution datasets are a fundamental prerequisite for communicating the impacts of population growth. ”

ArcGIS Living Atlas of the World is Esri’s scalable collection of out-of-the-box, up-to-date authoritative content in the form of maps, apps, and data layers, all accessible through a web browser and most products. Esri.

“The availability of 1 km WorldPop grid demographic datasets as imagery layers in ArcGIS Living Atlas of the World provides unprecedented convenience for polling and analyzing population anywhere on Earth,” said Charlie Frye , Esri’s chief cartographer. “The fact that these datasets no longer need to be downloaded or pre-assembled before use will result in substantial savings in time and money for any organization needing to understand recent demographic changes. ”

Queries can include the entire 21-year history of population changes for any group, including births and five-year age cohorts. The results of these queries can be analyzed spatiotemporally using Esri’s ArcGIS software to find patterns. Multitemporal datasets describe the spatial distribution at the grid cell level of the total population, age and sex cohorts, and population density.

“Age and sex gridded datasets provide invaluable information on the spatial and temporal distribution of specific demographic groups, such as children, the elderly and women of childbearing age, who are well known to be more vulnerable. than others, and therefore should be explicitly considered in decision-making and policy processes, ”said Dr Alessandro Sorichetta, associate professor of applied geospatial research at WorldPop.

The 1 km raster layers, organized by the WorldPop Spatial Data Infrastructure team led by Dr Maksym Bondarenko, are available in ArcGIS Living Atlas of the World for population per grid cell, population density per cell of grid and population by age and sex by cell grid.
