Census instructions matter, but genealogists do not always read them as often as they should. The image that is a part of this post comes from a set of instructions for the United States federal agricultural census schedules found on the www.census.gov website. It says that: “No farm will be reported of less than 3 acres, unless $500 worth of produce has been actually sold off from it during the last year.”
If you have an ancestor in the US agricultural census schedules, have you thought about what size and type of farm qualified? Was your ancestor who had a large truck garden from which sold produce supposed to have been enumerated?
Have you thought about reading the instructions?
Hard telling what you might learn.
