The USDA's Census of Agriculture provides data on the nation's farms every five years. A farm is defined as "any place from which $1,000 or more of agricultural products were produced and sold, or normally would have been sold, during the census year."
In Clark in 2017:
- there were 68 farms,
- the number of farms accounted for 0.3 percent of all Idaho farms, and
- the number of farms decreased 16 percent from ten years earlier.
