Acknowledgments

The construction of high-quality, global, geo-referenced population databases requires inputs of many different types. Investments by national statistical and mapping agencies to collect, maintain, and distribute population and administrative unit data are the first critical input. Each data provider is acknowledged in the country-level information and sources excel file. The next step of pulling these datasets together in a unified fashion requires a considerable amount of labor with skills in geography, demography, and database manipulation. GPWv4 is an effort that was largely implemented at CIESIN, with the advice and support of many partners. The current version builds on more than 20 years of Gridded Population of the World development, including the work described in the following papers:

  • The Global Distribution of Population: Evaluating the Gains in Resolution Refinement
  • Construction of Gridded Population and Poverty Data Sets from Different Data Sources
  • Transforming Population Data for Interdisciplinary Usages: From Census to Grid

This effort was led by a core group at CIESIN headed by Kytt MacManus and Susana B. Adamo. Erin Doxsey-Whitfield, Lisa Lukang, Linda Pistolesi, Olena Borkovska, John Squires, Jane Mills, Greg Yetman and Alyssa Fico were part of this core group.

We would like to thank the following individuals who contributed directly to the GPWv4 project: Ilyun Koh, Mou Jian Lee, Valentina Mara, Sandra R. Baptista, Hans Bosch, Robert Chen, Alex de Sherbinin, Branko Djapic, Bob Downs, Merlie Hansen, Marc Levy, Linda Pagliaroli, John Scialdone, Joe Schumacher, David Strom, Elisabeth Sydor, Sri Vinay, Jeremiah Trinidad-Christensen, Atiqur Rahman, Sneha Rao, Jared Talkin, Evan Drewry, Chenyang Zhao, Brina Sedel, Saloni Jain, and Lisa Tan.

Additionally, CIESIN would like to thank the many national statistics offices, mapping agencies, and other international organizations that provided data and support to the production of GPWv4.

GPWv4 was produced by CIESIN at Columbia University with primary support from the National Aeronautics and Space Administration under Contract NNG13HQ04C for the Socioeconomic Data and Applications Distributed Active Archive Center (DAAC) for the EOS Data and Information System (EOSDIS).
