The National Agricultural Statistics Service (NASS) collects and provides statistics for crop yields, trade, demographics, education, and many subsections, such as the National Conservation Defense Service.

"The USDA's National Agricultural Statistics Service (NASS) conducts hundreds of surveys every year and prepares reports covering virtually every aspect of U.S. agriculture. Production and supplies of food and fiber, prices paid and received by farmers, farm labor and wages, farm finances, chemical use, and changes in the demographics of U.S. producers are only a few examples.

• Report the facts on American agriculture....
