The National Agricultural Statistics Service’s 2007 Census of Agriculture revealed that the most common type of farm is lifestyle or retirement farms. NASS defines those farms as having less than 250 thousand in sales with the operator either being retired or with a primary occupation outside of farming. Statistics Director, Joe Prusacki, noted that 13 percent of the farms counted nationwide had started since 2002 and there were significant differences in those specific operations.
