HDX Dataset Deep Dive: WorldPop Gridded Population Datasets

OCHA’s Humanitarian Data Exchange (HDX) hosts almost 18,000 datasets from more than 1,300 sources. Our HDX Dataset Deep Dive series provides an opportunity to highlight the most interesting and useful datasets on the platform. In our December 2020 Deep Dive, hear from WorldPop about their Gridded Population Datasets.

An understanding of the numbers, characteristics and locations of human populations underpins operational work, policy analyses and scientific development globally across multiple sectors. However, traditional population data sources (such as censuses) have low granularity and are updated on the scale of decades. New data sources and recent methodological advances made by the WorldPop program now provide high resolution, open and contemporary data on human population distributions, allowing accurate measurement of local population distributions, compositions, characteristics, growth and dynamics, across national and regional scales.

Webinar participants will gain a detailed understanding of the methods used by WorldPop to develop high resolution population estimates that are shared on the WorldPop Open Population Repository and HDX. Participants will also learn how to use gridded population datasets in their own data products.
