title: Data Supplement: U.S. state-level projections of the spatial distribution of population consistent with Shared Socioeconomic Pathways.

description: These data are to supplement the following in-press publication: Zoraghein, H., and O'Neill B. (2020). U.S. state-level projections of the spatial distribution of population consistent with Shared Socioeconomic Pathways. Sustainability. The data herein were generated using the `population_gravity` model which can be found here: https://github.com/IMMM-SFA/population_gravity CONTENTS: <strong>zoraghein-oneill_population_gravity_inputs_outputs.zip</strong> contains a directory for each U.S. state for inputs and outputs <strong>inputs</strong> contain the following: <strong>&lt;state-name&gt;_&lt;urban or rural&gt;_&lt;yr&gt;_1km.tif: </strong> Urban and Rural population GeoTIF rasters at a 1km resolution value per grid cell: number of humans (float) crs: EPSG:102003 - USA_Contiguous_Albers_Equal_Area_Conic - Projected nodata value: -3.40282e+38 <strong>&lt;state-name&gt;_mask_short_term.tif: </strong> Mask GeoTIF rasters at a 1km resolution that contain values from 0.0 to 1.0 for each 1 km grid cell to help calculate suitability depending on topographic and land use and land cover characteristics value per grid cell: values from 0.0 to 1.0 (float) that are generated from topographic and land use and land cover characteristics to inform suitability as outlined in the companion publication crs: EPSG:102003 - USA_Contiguous_Albers_Equal_Area_Conic - Projected nodata value: -3.40282e+38 <strong>&lt;state-name&gt;_&lt;ssp&gt;_popproj.csv: </strong> Population projection CSV files for urban, rural, and total population (number of humans; float) for SSPs 2, 3, and 5 for years 2010-2100 <strong>&lt;state-name&gt;_coordinates.csv: </strong>CSV file containing the coordinates for each 1 km grid cell within the target state.
