«Forty-five percent of farmland is in small family farms, and nearly half (46 percent) of this land is found in operations that own all the land they operate [as opposed to renting some].»

So, like… 21% of farmland is in the stereotypical family farm. Which seems like a lot to me, actually (i.e., higher than I would have expected).

«Ten percent (93 million acres) of all land in farms is expected to be transferred during 2015-2019, most of which (6 percent) will change hands through gifts, trusts, or wills. Of all land expected to be transferred, only about a quarter (21 million acres) will be sold between nonrelatives. »

Family selling/transferring to each other. Worth remembering when I get spun up on racism again in about an hour.

«The reduction in self-employed and family labor through 1990 was more rapid than the decline in hired labor. According to data from the Farm Labor Survey (FLS) of USDA’s National Agricultural Statistical Service (NASS), the number of self-employed and family farmworkers declined from 7.60 million in 1950 to 2.01 million in 1990, a 74-percent reduction. Over this same period, average annual employment of hired farmworkers—including on-farm support personnel and those who work for farm labor contractors—declined from 2.33 million to 1.15 million, a 51-percent reduction. As a result, the proportion of hired workers has increased over time.»

A little more on family farms:

«Off-farm sources—including wage income, nonfarm business earnings, dividends, and transfers—are the main contributors to income for most farm operator households in the United States, including the majority of residential and intermediate farm households (see glossary for definitions [“farm typology”, if you follow that link]). These households derive less than half their income from farming and are not as affected by changes in farming costs and returns as are large commercial farms but may be more susceptible to changes in the broader economy.»
