California agriculture and economy, 2009

California agriculture is more than farming and is liked to the rest of the economy About 600 thousand direct jobs in production and processing and about 1.3 million including the ripple effects. About $43 billion in direct GDP and about $112 billion including ripple effects. Overall agriculture accounts for about 6% of the economic activity in California Farming itself is more than half of that with fruit leading the way, but California farming has great diversity

Central Valley agriculture and economy, 2009

Central Valley agriculture is large and diverse comprising a significant share of the whole economy About 22% of Central Valley jobs are tied to agricultural production and processing, about 40% linked to farm processing About 9% of GDP is tied directly to agriculture and this grows to about 21% when we include the ripple effects. Fruit, tree nuts, vegetables and dairy are the big contributors to farm value added and employment.

Southern California agriculture and economy, 2009

Agriculture also contributes significantly to the Southern California economy About 460 thousand jobs and $42 billion in GDP derived from agricultural production and processing when ripple effects are included Farming in Southern California accounts for about a quarter of these totals in the region. Greenhouse and nursery, fruit and vegetables are all major contributors.
