Gridded Population of the World (GPW), v3

Acknowledgment and Credits

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 table of country-specific information.  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.  GPW version 3 and GRUMPv1 were efforts that were largely implemented at CIESIN, but the detailed credits for each product follows.*   This work builds on 10 years of prior efforts, which are described within the documentation.

This effort was led by a core group at CIESIN and CIAT headed by Deborah Balk and Gregory Yetman of CIESIN.  Melanie Brickman (CIESIN), Lisa Lukang (CIESIN), and Glenn Hyman (CIAT), were also part of this core group.
