Agricultural Resource Management Survey (ARMS): Resource Regions

ERS U.S. Farm Resource Regions

The U.S. farm sector consists of a highly diverse set of businesses and farm households committed to living in rural areas and engaging in farm economic activities. Since the early 1900's, USDA analysts have sought to identify patterns in U.S. farming that might further the understanding of differences in financial performance of farms and the economic well-being of farm households.

USDA's Economic Research Service (ERS) constructed regions that depict geographic specialization in production of U.S. farm commodities. The ERS regions are derived from four sources:

• the Farm Production Regions,
• a cluster analysis of U.S. farm characteristics (Sommer and Hines),
• the USDA Land Resource Regions, and
• National Agricultural Statistics Service (NASS) Crop Reporting Districts.

Data Presented by ERS Farm Resource Regions

• Commodity Costs and Returns
• Environmental Quality Incentives Program Data
• Agricultural Resource Management Survey Data
• Farm and Farm-related Employment Data

Background

Farm Production Regions

The older Farm Production Regions, in following State boundaries, necessarily group unlike areas together because a single State often encompasses different soils and typography. For example, the old Appalachian Region, comprised of Tennessee, Kentucky, North Carolina, and Virginia, contains the Appalachian mountains, Piedmont, and Coastal Plain areas, all of which have quite different agriculture.

Patterns of Agricultural Diversity (Sommer and Hines)

County clusters, based on types of commodities produced, have shown that a few commodities tend to dominate farm production in specific geographic areas that cut across State boundaries. The climate, soil, water, and topography in localized geographic areas tend to constrain the types of crops and livestock that will thrive there.

USDA Land Resource Regions

In constructing the ERS production regions, analysts identified where areas with similar types of farms intersected with areas of similar physiographic, soil, and climatic traits, as reflected in USDA's Land Resource Regions.

NASS Crop Reporting Districts

ERS analysts then conformed these intersecting areas to follow the boundaries of NASS Crop Reporting Districts (CRD), which are aggregates of counties. With more and more data available at the county level, geographic representations need no longer be constrained to follow State boundaries.
