POPULATION DENSITY

This image shows the population density of 
the Circum-Pacific region.  The colors 
represent the number of people per square 
kilometer.  Black and brown areas are the 
most densely populated, and yellow and 
beige areas are the most sparsely 
populated.  The file 'COLORMAP.JPG' 
(located in 'HAZPAC_ARCVIEW\DATA\IMAGE') 
contains a legend for this image.  The 
original grid theme was downsampled to 
2.5-minute by 2.5-minute resolution before 
conversion to a JPEG image.  The data were 
developed using census information, 
proximity to roads, hill slope, lights at 
night, and land use.  The data are from 
Oak Ridge National Laboratory (2000).
