The statistical census data are summarized at the state, county, and U.S. levels and are available in a digital format. The Research and Development Division of NASS modified generalized state boundaries to show geographic areas for which the 2002 Agricultural Census statistics are reported at the state level. These state level boundary files were used in the production of the 2002 Census of Agriculture, Agricultural Atlas of the United States. The boundary files can be employed in a Geographic Information System (GIS) with the 2002 Agricultural Census statistical data by using the Agricultural Census state codes to associate the state level spatial entities with the state level statistical data. Purpose: The boundaries are intended for geographic display and analysis at the state level. The boundary data are designed for small scale thematic mapping applications at a scale of 1:20,000,000 or smaller (e.g., 1:50,000,000, etc.). The state level boundaries are provided "as is". The USDA/NASS does not warrant the results you may obtain using the Agricultural Census state level boundary data. Supplemental_Information: These Agricultural Census state level boundary files may be used with statistical data in the 2002 Census of Agriculture, Volume 1, Geographic Area Series, Parts 1 - 51.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Unmodified entities have entity codes and names which conform to the Federal Information Processing Standard 5-2. Area values in square miles are derived from land polygon area values from the U.S. Census Bureau's TIGER database. Logical_Consistency_Report: No topological checks were performed on the data. Completeness_Report: The generalized data do NOT include 1) boundaries for the Aleutian Islands in the Eastern Hemisphere, 2) boundaries for Hawaiian Islands west of -160.25 degrees longitude, 3) very small polygons because of coordinate thinning, and 4) water polygons. This data set provides the land area in square miles and number of acres for each state equivalent. The land area values are based on the area of land polygons from the U.S. Census Bureau's TIGER database. If a state is composed of several polygons, the area value assigned to each polygon is the land area value of the entire state (for the purpose of choropleth mapping). The state level boundary for Maryland was modified to include the District of Columbia (D.C.), because Agricultural Census data for D.C. are not reported separately. State level Federal Information Processing (FIPS) codes are used to identify states. Because Maryland and D.C. state boundaries were aggregated, Maryland's FIPS code 24 represents Maryland (24) and D.C. (11). Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The state level boundary data are highly generalized and suitable for use in small scale (1:20,000,000) thematic mapping applications. No accuracy tests were performed.

Source_Currentness_Reference: publication date Source_Citation_Abbreviation: StGenAll_D02 Source_Contribution: spatial and attribute information Process_Step: Process_Description: 1 - Procurement of spatial and attribute data. The original generalized unprojected county level boundary data files and a separate county area-perimeter data file were obtained by special request from the U.S. Bureau of the Census, Geography Division. The spatial data file format is Environmental Systems Research Institute's (ESRI) ArcView shapefile format. The area data file format is dBASE. Hawaii's county boundary files (scale 1:5000000) were downloaded from the U.S. Census Bureau's Cartographic Boundary Files web site. Source_Used_Citation_Abbreviation: USCOBDY Source_Used_Citation_Abbreviation: USCOAREA Source_Used_Citation_Abbreviation: HICOBDY Process_Date: 2001 Process_Step: Process_Description: 2 - Creation of state boundary files. State boundary files were created from county level boundary files by dissolving boundaries between counties which had the same state FIPS code. The District of Columbia was assigned Maryland's state FIPS code. The Maryland and D.C. state level boundaries were aggregated by dissolving boundaries between D.C. and Maryland which had the same state FIPS code. Source_Used_Citation_Abbreviation: USCOBDY Source_Used_Citation_Abbreviation: HICOBDY Process_Date: 2001 Source_Produced_Citation_Abbreviation: USSTBDY Source_Produced_Citation_Abbreviation: HISTBDY Process_Step: Process_Description: 3 - Creation of separate spatial files. The single state level boundary file was split into 4 state boundary files: Alaska, Puerto Rico, continental U.S., and Hawaii, (Hawaii's more detailed state boundary was used in place of Hawaii's generalized state boundary. Islands west of -160.25 degrees longitude were deleted). Source_Used_Citation_Abbreviation: USSTBDY Source_Used_Citation_Abbreviation: HISTBDY Process_Date: 2001 Source_Produced_Citation_Abbreviation: MULTIUSSTBDY Process_Step: Process_Description: 4 - Modification of state level boundary file fields. A field was added to the boundary files and populated with the state names in upper case. A field was added to the boundary files and populated with the state abbreviations. The Area field of the boundary files contained erroneous values, so zeros replaced the area values. Several unnecessary fields of the boundary files were deleted (Perimeter, etc.). Source_Used_Citation_Abbreviation: MULTIUSSTBDY Process_Date: 2002 Source_Produced_Citation_Abbreviation: AGUSSTBDY Process_Step: Process_Description: 5 - Calculation of state land area. A state land area file was made from a copy of the area-perimeter file. A field was added to the state land area file to contain the state area in square miles and was populated by summing the county land area values (in square miles) for each state. The state land area values for Maryland and D.C. were added together. A field was added to the state land area file to contain the state acreage. The land area values (in acres) of states were calculated by multiplying the state land area (in square miles) by 640 (1 square mile contains 640 acres). Source_Used_Citation_Abbreviation: USCOAREA Process_Date: 2002 Source_Produced_Citation_Abbreviation: SQMIACREUSST Process_Step: Process_Description: 6 - Modification and update of state level boundary file. The Agricultural Census state boundary files were modified to contain fields for state area in square miles and acreage. The new area fields were populated with data from the state land area file. Source_Used_Citation_Abbreviation: AGUSSTBDY Source_Used_Citation_Abbreviation: SQMIACREUSST Source_Produced_Citation_Abbreviation: AREAUSSTBDY Process_Date: 2002 Process_Step: Process_Description: 7 - Creation of single spatial file. The separate Agricultural Census state level boundary files for Alaska, Hawaii, Puerto Rico and the continental U.S. were merged into a single Agricultural Census state level boundary file. Source_Used_Citation_Abbreviation: AREAUSSTBDY Source_Produced_Citation_Abbreviation: ALLUSSTBDY Process_Date: 2003 Process_Step: Process_Description: 8 - Modification of field names. Field names were modified and some fields were rearranged in the Agricultural Census state level boundary file.
