Yolo County is one of the original 27 counties created when California became a state in 1850; it has been suggested that the name “Yolo” is derived from the word “yoloy,” a Native American word signifying "a place filled with rushes." Yolo County is primarily composed of the four cities of Davis, Woodland, West Sacramento and Winters. Other locations of note include Esparto and the Capay Valley. Other than these cities, most of the land is used for agriculture. Davis rests in the southwestern edge of Yolo on its border with Solano County. Yolo County is home to a booming Tomato business in California and accounts for 90% of Tomatoes produced in the United States.

Woodland is the county seat, although it was originally Washington (later called Broderick, which in turn was absorbed into West Sacramento).
