*Here’s what NASS says about such omissions: “If publishing a particular data item would identify an operation (for example, if there is only one producer of a particular commodity in a county), NASS does not publish the information. In such cases, the data are suppressed and shown as ‘(D),’ meaning ‘withheld to avoid disclosing data for individual operations.’"
