Census Economic Data from Agroecological Resource Area (ARA) Database
The ARA polygons were manually overlaid on census Enumeration Area (EA) maps. Only EAs which were at least 70 percent within one ARA were included in the analysis. Individual farm records were processed through a farm typing routine discussed in Huffman et al. (1992), to produce statistics for each farm type within each ARA. The economic parameters in this data file are averages of the median values for all farm types within each polygon. This data file is valid only for dryland systems.
N.B. Sales and expenses information pertain to the year prior to the Census year, while capital values and livestock pertain to the Census year.
* Denotes data for the 1981 or 1986 Census, e.g. ECONOMICS81.DAT.

|Item Name||Description||Reporting Units|
|VALLND||Value of Land and Buildings||as % of total value|
|VALLIV||Value of Livestock||as % of total value|
|VALMACH||Value of Machinery and Equipment||as % of total value|
|FUEL||Cost of Fuel (machinery + heating and drying)||as % of expenses|
|FERT||Cost of Fertilizer||as % of expenses|
|SALINV||Sales to Investment Ratio (total sales divided by total capital investment)|
|SALEXP||Sales to Expenses Ratio (total sales divided by operating expenses)|
|TVALHA||Total Value (land, buildings, machinery, equipment, livestock)||$/ha|
|GMARHA||Gross Margin ((total sales - operating expenses) divided by farm size)||$/ha|
|REGION||Agricultural Resource Region -- a grouping of ARAs to represent areas of similar agroclimatic potential.|
Farm size is the total farm area, including owned and rented land. For Total Value, the Census respondents estimate the present market value of their owned land, buildings, machinery and equipment. TVALHA = Total value divided by farm size. Livestock value (cattle, pigs, sheep, bees, poultry and others) is a derived variable, calculated from information provided on the number of livestock. Total sales includes sales of all agricultural products, shares from tenants, cash advances for stored crops, Marketing Board or Agency payments, income from custom work and rebates. Sales of capital items (e.g. machinery) or forest products are not included. Operating expenses includes cash rent, share rent, cash wages, feed, fertilizer, chemicals, custom work, fuel, repairs, electricity and other miscellaneous expenses. It does not include livestock purchases, veterinary bills, telephone and postage, professional services, insurance, Marketing Board fees, taxes, interest payments, mortgage payments nor depreciation.
