From the passage provided, extract the more recent available annual revenue from agriculture in dollars.

Context: Agriculture is an important sector in California's economy. Farming-related sales more than quadrupled over the past three decades, from $7.3 billion in 1974 to nearly $31 billion in 2004. This increase has occurred despite a 15 percent decline in acreage devoted to farming during the period, and water supply suffering from chronic instability. Factors contributing to the growth in sales-per-acre include more intensive use of active farmlands and technological improvements in crop production. In 2008, California's 81,500 farms and ranches generated $36.2 billion products revenue. In 2011, that number grew to $43.5 billion products revenue. The Agriculture sector accounts for two percent of the state's GDP and employs around three percent of its total workforce. According to the USDA in 2011, the three largest California agricultural products by value were milk and cream, shelled almonds, and grapes.

Answer: In 2011, California's agricultural product revenue was $43.5 billion.
