Title:
2022
Census of Agriculture County-Level Boundaries, (coUSAKHI_LAEA_2022.shp -.shx,
-.dbf, -.sbn, -.sbx, -.prj)
Abstract:
The
United States Department of Agriculture (USDA), National Agricultural
Statistics Service (NASS) conducted an Agricultural Census in 2022. The
statistical census data are summarized at the county, state, and U.S. levels
and are available in a digital format. The Research and Development Division of
NASS modified generalized county boundaries to show geographic areas for which
the 2022 Agricultural Census statistics are reported at the county level. These
NASS county-level boundary files were used in the production of the 2022 United
States Census of Agriculture, Agricultural Census Web Maps. The boundary files
can be employed in a desktop or online Geographic Information System (GIS) with
the 2022 Agricultural Census statistical data by using the NASS Agricultural
Census county codes to associate the NASS county-level spatial entities with
the NASS county-level statistical data.
Supplemental_Information:
These
NASS Agricultural Census county-level boundary files may be used with
statistical data in the 2022 Census of Agriculture, Volume 1, Geographic Area
Series, Parts 1 - 50.

The boundaries are intended for geographic display and analysis at the county- 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 county-level boundaries are provided "as is". The USDA/NASS does not warrant the results you may obtain using the Agricultural Census county-level boundary data.

1 - Creation of NASS Agricultural Census counties and
summation of land area. Use county boundary and attribute source files provided
by the Bureau of the Census. The county-level boundaries show geographic areas
for which 2022 Agricultural Census statistics are reported. Certain individual
counties were assigned the ANSI code of a designated adjacent or surrounding
county. County boundaries were dissolved on the NASS Agricultural Census county
(ANSI) codes and county land area values (in square miles) were summed - this
modified only the land area values for aggregated (dissolved) counties in AK,
HI, MD, MO, VA. The following is a list of counties with modified boundaries.
The Agricultural Census county codes and associated (=) U.S. county ANSI codes
are identified below. 02010 = 02013, 02016, 02050, 02060, 02070, 02150, 02158,

2 - Modification and update of Agricultural Census
county-level boundary file. The 2022 Agricultural Census county boundary files
were updated with 2022 attribute values. The Agricultural Census county-level
boundary files were modified to contain a field for county land area in acres.
The county acreage fields were populated by multiplying the county land area in
square miles by 640 (1 sq. mi. = 640 ac.). Data sources used in this process:

3 - Create coastline of the 2012 1:20,000,000 scale
Agricultural Census boundary file. Dissolve the 2012 1:20,000,000 scale
Agricultural Census state-level boundary file to create a coastline boundary
file (more detailed than 2022 1:20,000,000 scale coastline). Data sources used

4 - Clip 2022 Agricultural Census county-level boundary
file. Projected 2012 1:20,000,000 US coastline boundary file and used it to
clip the 2022 1:20,000,000 scale NASS Agricultural Census county-level boundary
file. Clipping the 2022 county-level boundary file by the 2012 coastline adds
more detail (e.g., coastal inlets) to the 2022 county-level boundary file. Data

5 - Extract and project clipped NASS Agricultural Census
county-level boundary files. Extracted NASS 2022 Agricultural Census
county-level boundary files to create separate shapefiles for the continental
US, AK, and HI. Reprojected shapefiles to custom Albers Equal Area projections.

6 - Project NASS Agricultural Census county-level boundary
file to Lambert Azimuthal Equal Area. Merged separate shapefiles for the

to Lambert Azimuthal Equal Area; added Census year attribute. Data sources used
