Share of gross is a past year, all observed: that year's rent, that year's county corn yield of the same practice and the state price received, USDA NASS.

Counties that share a stretch of boundary. A rent from an older survey year carries its year and stays out of the median; one more than three survey years old shows n/a. The corn median here needs 15 published years, so a county with fewer shows n/a even where its own page gives a median.
