Estimated Value of Agricultural Operations (EVAO), 1996-1997

\r\n\r\nThe geography of this dataset is Australian statistical local area (SLA). The\r\ndata relates to Estimated Value of Agricultural Operations (EVAO) as a median\r\nvalue for each SL for each farm at a scale of 25000000. The estimated value\r\nof agricultural operations is a measure of gross farm income and this data\r\nrepresents all farm establishments with an EVAO greater than $5,000.The data\r\nis presented at a scale of 25000000.
