Identification_Information: Citation: Citation_Information: Originator: Steve Hanser, USGS-FRESC, Snake River Field Station Publication_Date: 2004 Title: Population Density in the Western United States (Individuals / ha) Geospatial_Data_Presentation_Form: raster digital data Online_Linkage: http://sagemap.wr.usgs.gov/ftp/regional/usgs/popdens_hf.zip Description: Abstract: This map of human habitation was developed, following a modification of Schumacher et al. (2000), by incorporating 2000 U.S Census Data and land ownership. The 2000 U.S. Census Block data and ownership map of the western United States were used to correct the population density for uninhabited public lands. All census blocks in the western United States were merged into one shapefile which was then clipped to contain only those areas found on private or indian reservation lands because human habitation on federal land is negligible. The area (ha) for each corrected polygon was calculated and the 2000 census block data table was joined to the shapefile. In a new field, population density (individuals/ha) corrected for public land in census blocks was calculated . SHAPEGRID in ARC/INFO was used to convert population density values to grid with 90m resolution. Purpose: Spatially represent human population density throughout the western United States Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 2000 Currentness_Reference: publication date Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -125.839147 East_Bounding_Coordinate: -99.737876 North_Bounding_Coordinate: 49.371521 South_Bounding_Coordinate: 30.785066 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: Population density Theme_Keyword: Population Theme_Keyword: Census 2000 Theme_Keyword: TIGER/line Place: Place_Keyword_Thesaurus: None Place_Keyword: Washington Place_Keyword: Oregon Place_Keyword: California Place_Keyword: Idaho Place_Keyword: Nevada Place_Keyword: Utah Place_Keyword: Arizona Place_Keyword: Montana Place_Keyword: Wyoming Place_Keyword: Colorado Place_Keyword: New Mexico Place_Keyword: Western US Access_Constraints: None Use_Constraints: None.
