This summary, which is published annually, is based on the annual Crop Reports compiled by the California County Agricultural Commissioners. These reports provide the most detailed annual data available on agricultural production by county.

Basic data collected by the Agricultural Commissioners and their staffs are compiled from many sources. Sources vary from county to county. Examples of data sources include growers' surveys, regulatory and inspection data, shipment data, industry assessments, etc.

The amount of detail varies by county. For instance, one county may list grapes only; another may show grapes by raisin, table, and wine; another may list a further breakdown, such as canned, crushed, dried, fresh, and juice. The data were coded at the detail level.

Users are reminded that price data reflect the average price received by growers, except fresh market fruits and vegetables, which are on a packed and ready to ship basis (F.O.B. = Free-On-Board).

The sum of other counties includes only those counties providing the California Department of Food and Agriculture a listing of commodities that cannot be published at the county level due to disclosure of confidential information. However, data can be published when combined with other counties. Please be aware that the count is shown as one in all cases.

Credit is due the County Agricultural Commissioners and their staffs for preparing the annual county Crop Reports upon which this compilation is based.
