A unique program in the state recognizes farm families who have owned their property for over a century. The North Carolina Department of Agriculture and Consumer Services' Century Farm Families program began in 1970 under the leadership of then agriculture commissioner Jim Graham. That year over 800 farms were identified whose owners were able to provide proof of 100 years of continuous ownership. In 2005, the number is around 1,500 farms, with an average of two or three farms joining the program each month. The greatest concentration of Century Farms is in Johnston, Nash, Robeson, Sampson, Duplin, and Alamance Counties. Of North Carolina's 100 counties, only five do not have Century Farms--Dare, Jackson, New Hanover, Swain, and Yancey.
