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 interactive mapper above
gives a preview of the Gridded Population of the World data sets.
To obtain population estimates within a user-defined region, use
our Population Estimation Service. For more
advanced visualization and overlay with other related data sets,
you may use the stand-alone SEDAC Map
Client.
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.
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. 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. For a list of the many individuals who contributed time,
effort, and expertise to these data products, please see the Acknowledgments and Credits.
