High resolution population grid for the entire United

We have developed a 30 m resolution population grid for the entire United States on the basis of the 2010 Census block-level data. Dasymetric model was used to disaggregate population in each of ~ 11 millions census blocks into their constituent 30m cells. The model uses land cover (NLCD 2011) and the new U.S.–wide land use dataset as auxiliary variables. Both auxiliary datasets have 30 m resolution; the land use dataset permits distinctions between populated and unpopulated impervious areas. Visual comparison of population density maps based on our model with the population maps based on previous U.S.–wide population density resources indicates much better utility of the new grids. Our population grid is accessible (for exploration and download) through SocScape – an internet-based application available a
