Agriculture is a major component of the New York economy. As of the 2012 census of agriculture, there were over 35,000 farms covering an area of 7 million acres (28,000 km2) which contributed $5.4 billion in gross sales value and $1.2 billion in net farm income to the national economy. Dairy farming alone accounted for $2.5 billion or 45% of sales. The Finger Lakes region is the center of state agriculture, and the state is a top-ten national producer of cow milk, apples, grapes, onions, sweet corn, tomatoes, and maple syrup.
