Data from the Oak Ridge National Laboratory, LandScan Global Population 1998 and 2000 Database.
The LandScan Global Population Project is a worldwide population database at 30" X 30" (arc second) resolution for estimating ambient populations at risk. Best available census counts are distributed to cells based on probability coefficients which, in turn, are based on road proximity, slope, land cover, and nighttime lights. Global coverage has been completed. Verification and validation (V&V) studies have been conducted routinely for all regions and more extensively for portions of the Middle East and the Southwestern United States.
