GLOBAL Gridded Population Maps and Data

Gridded Population of the World, version 3 (GPWv3) is the third edition of a FREE large-scale data product that demonstrates the spatial distribution of human population across the globe. This includes a major update to the underlying population and spatial data, and in its wake, additional updates have been made, for example, to the Africa accessibility model. Similarly, in collaboration with the Food and Agriculture Organization of the United Nations (FAO), CIESIN and CIAT have constructed a gridded population projection to 2015.

Gridded Population of the World, version 3 (GPWv3) and the Global Rural-Urban Mapping Project (GRUMP) are the latest developments in the rendering of human populations in a common geo-referenced framework, produced by the Center for International Earth Science Information Network (CIESIN) of the Earth Institute at Columbia University.

The Maps & Data download page:GPWv3 depicts the distribution of human population across the globe. It is the most detailed version of GPW to date with more than three times the amount of data as version 2, and includes population estimates to 2015. GRUMP builds on GPWv3 by incorporating urban and rural information, allowing new insights into urban population distribution and the global extents of human settlements.

A Sample Map:

Developed between 2003 and 2005, GPWv3 and GRUMP provide globally consistent and spatially explicit human population information and data for use in research, policy making, and communications. GRUMP is currently in its alpha edition. Check back in early 2006 for updates. For more information, please see the projects’ Description and History. We appreciate user feedback, including copies of published papers and maps that use our data; please review the data usage policy.
