High-Resolution Population Grids for the Entire Conterminous United States

To have a more complete awareness of the global environment and how it changes, remotely sensed data pertaining to the physical aspects of the environment need to be complemented by broad-scale demographic data having high spatial resolution. Although such data are available for many parts of the world, there are none available for the United States. Here we report on our ongoing project to develop high-resolution (30–90 m/cell) population/demographic grids for the entire conterminous United States and to bring them into the public domain. Two different, dasymetric modeling-based approaches to disaggregation of block-level census data into a fine grid are described, and resulting maps are compared to existing resources. We also show how to utilize these methods to obtain racial diversity grids for the entire conterminous United States. Our nationwide grids of population and racial diversity can be explored using the online application SocScape at http://sil.uc.edu.
