It is taken every five years. The census of agriculture is the only tool that gives a complete count of every operation in our nation. It is also the only source of uniform, comprehensive information on agricultural production, inventories, sales, and expenses for all states and counties. I could simply say that your response is required by law, and there are penalties for not responding. But that's not the most important reason you should respond.
Farmers benefit both directly and indirectly from responding to the census of agriculture.
Farmers can use census data to spot trends that will help them decide which crops to grow or livestock to raise. Agribusinesses use the data to identify sales territories and plot the most effective locations for retail outlets and value-added facilities. Farm organizations use the results to develop farm programs and policies. U.S. and State Departments of Agriculture use the information to establish programs and determine eligibility for those programs. Congress uses the information to develop or change farm legislation.
