Oil and agriculture dominate the economy. In fact, Yoakum County is in the top four counties in the state in crude oil production. Cotton is the primary agricultural cash crop. Other agricultural income comes from peanuts, watermelons. grain sorghum, wheat, chili peppers, and beef cattle.

Yoakum County continued to be a cattle county with very little crop production until the early 1940's when irrigation wells and sprinkler systems came into being. The development of irrigation water has had a more dramatic influence on the agricultural economy of the county than any other factor. The water is derived from the Ogallala Aquifer.

Yoakum County, like other Texas Counties, is concentrating on growing a strong educational system and developing a strong economy that will prepare its citizens and its children for the 21st century.
