You can access it here. What struck me first, from the CRS report, was the rapid increase in farm household income from off farm sources, to the point that off-farm accounted for easily 3 or 4 times as much income as farm sources.
Then, as I tried to find a way to get the image into this post, and failed, I found this ERS spreadsheet. We all remember the difference between "mean" and "median", right. According to the table the median farmer had no income from farming in the years 2013-2018.
That's weird, but this helps to explain it (from a Rural Development Perspectives article)
Almost 90 percent of elderly operators' average household income came from off-farm sources, with nearly half of their off-farm income coming from "other off-farm income," which includes Social Security. Another 19 percent of their off-farm income came from interest and dividends, reflecting savings and investments by these households during earlier years. Unlike elderly operators, operators under age 65 received most of their off-farm income from wages, salaries, or self-employment.That was my mother after my father died--for a number of years she continued the poultry operation, but SS income was really the basis of her livelihood. But we don't think of these situations when discussing "farmers".
