Abstract:
The Global 15x15 Minute Grids of the Downscaled Population Based on the Special Report on Emissions Scenarios (SRES) B2 Scenario, 1990 and 2025, are geospatial distributions of the downscaled population per unit area (population densities). These global grids were generated using the Country-level Population and Downscaled Projections Based on the SRES B2 Scenario, 1990-2100 data set, and CIESIN's Gridded Population of World, Version 2 (GPWv2) data set as the base map. The 1990 GPW was used as the base distribution and the country-level downscaled projections were used to replace population estimates of 1990 in GPW and 2025. The fractional distribution of the population at each grid cell is the same as the 1990 GPW, sub-nationally. This data set is produced and distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).
Purpose:
To provide a gridded data on country-level population and downscaled projections based on the SRES B2 marker scenario.

Data Set Credit:
Country-level Population and Downscaled Projections for the SRES B2 Scenario, 1990-2100, was developed at CIESIN, Columbia University, by Stuart R. Gaffin, Xiaoshi Xing, and Greg Yetman. Wolfgang Lutz and Anne Goujon of International Institute for Applied Systems Analysis (IIASA) developed and supplied the population downscaling for the A1, B1 and A2 SRES scenarios. This work, including access to the data and technical assistance, is provided by CIESIN, with funding from the National Aeronautics and Space Administration under Contract NAS5-98162 for the Operation and Maintenance of the Socioeconomic Data and Applications Center (SEDAC).
