![]() ![]() Further details on the methods can be found in Tatem et al. ![]() WorldPop integrates small area data on the distribution of women of childbearing age and age-specific fertility rates to map the estimated distributions of births for each 1x1km grid square across all low and middle income countries. The health and survival of women and their new-born babies in low income countries is a key public health priority, but basic and consistent subnational data on the number of live births to support decision making has been lacking. Older datasets produced for specific individual countries and continents, using a set of tailored geospatial inputs and differing "top-down" methods and time periods are still available for download here: Individual countries and Whole Continent. Constrained individual countries 2020 UN adjusted ( 100m resolution ): Consistent 100m resolution population count datasets created usingĬonstrained top-down methods for all countries of the World for 2020 and adjusted to match United Nations national Constrained individual countries 2020 ( 100m resolution ): Consistent 100m resolution population count datasets created usingĬonstrained top-down methods for all countries of the World for 2020. ![]() Unconstrained global mosaics 2000-2020 ( 1km resolution ): Mosaiced 1km resolution versions of the "Unconstrained individual countries 2000-2020" datasets.

Unconstrained individual countries 2000-2020 ( 1km resolution ): Consistent 1km resolution population count datasets created using Please make sure you read the Top-down estimation modelling overview page to decide on which datasets best meet your needs.ĭatasets are available to download in Geotiff and ASCII XYZ format at a resolution of 3 and 30 arc-seconds (approximately 100m and 1km at the equator, respectively): With either the unconstrained or constrained top-down disaggregation method used. The remaining datasets in the links below are produced using the " top-down" method, They can also be visualised and explored through the woprVision App. These are 100m resolution gridded population estimates using customized methods (" bottom-up" and/or " top-down") developed for the latest data available from each country. Please make sure you have read our Mapping Populations overview page before choosing and downloading a dataset.īespoke methods used to produce datasets for specific individual countries are available through the WorldPop Open Population Repository (WOPR) link below. WorldPop produces different types of gridded population count datasets, depending on the methods used and end application. ![]()
