Adams County

Adams County is located in southeastern Washington. As of 2011, the population is estimated to be 18,950. The county seat is in Ritzville and its largest city is Othello. 

Since its creation in 1883, Adams County has been known as an agricultural and livestock ranching area. Wheat, corn, apples and potatoes are among the crops grown in the area. The vegetable and fruit-processing industry, especially potato processing and French fry manufacturing provides most of the county's industrial employment.  As of 2006, about 10 percent of the French fries consumed in American are processed in Othello.

The county saw its first railroad in 1881, which helped spur settlement and economic development. By 1909, Adams County was known as the "bread basket of the world".  The county is still one of the largest wheat producers in the state. 

In addition to agriculture and livestock ranching, the county has unique recreation and tourism draws including an annual Sandhill Cranes Festival in March, where thousands of bird watchers attend.

As of 2006, Adams County's population was 52 percent Hispanic, with most Hispanic residents being of Mexican heritage.
