2. Data Sources
USDA’s Farm Production Expenditures Summary ( documentID=1066)
Available yearly
5 Region, 15 “core” states, does not include Alaska or Hawaii
USDA’s Census of Agriculture (
Taken once every 5 years census currently available, census available Feb 2019
Data is not readily available in Excel format, it will need to be requested from the USDA
Ag census website is being updated on 10/1, so more data (outside of PDF or text format) may be available at that time

3. Proposed Allocation Steps
Develop agricultural equipment allocation data for Alaska and Hawaii based on the 2012 Census of Agriculture’s “Gasoline, Fuels, and Oils Purchased” dollar values
Allocation data for all other states are developed at the regional-level, for the 5 regions for which the 2016 Farm Production Expenditures Summary develops data (i.e., Atlantic, South, Midwest, Plains, and West).  These data will be based on “Petroleum Fuel and Oil” expenditures in each region.
Allocate regional proportions further down to the state-level for the 15 states for which “Petroleum Fuel and Oil” expenditures data are reported in the 2016 Farm Production Expenditures Summary report.
Use the 2012 Census of Agriculture’s “Gasoline, Fuels, and Oils Purchased” dollar values to allocate the state/regional data compiled above down to the county-level.
