This summary 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 grower surveys, regulatory and inspection data, shipment data, industry assessments, etc. The amount of detail varies by county. The data were coded at the detail level. The sum of other counties included only those counties that provide 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.
