I don't spend a lot of time on it, just give a good ballpark estimate, I think that is all they are looking for anyway. Maybe I should be a little more paranoid, but I doubt that anyone has time to compare census answers against tax records. If the Ag. Dept. was working with the IRS, they really wouldn't need to ask about financial information. But I suppose if enough people don't fill out the forms that will be the next step.
