Farmers are regularly surveyed by the USDA on a variety of information regarding their operations, including weekly condition and progress surveys, production/yields, prices received, cost inputs and much more for just about every agricultural product produced in the US. Some USDA datasets span over 100 years. Its why scientists all over the world often focus on US agriculture; because the dataset is so comprehensive compared to the ag records of other countries. So, I don't buy the "fiscal and program resources" reasoning for removing the question because the framework is already in place and has been for a long time.
They axed the question because the data is expected to show that bee colonies are declining at an alarming rate which is bad for Trump's "Keep America in the 20th century" policy. As bayviking said, "ignorance is bliss."
