GONZALES, Calif. — It looks like a century-old picture of farming in California: a few dozen Mexican men on their knees, plucking radishes from the ground, tying them into bundles. But the crews on Sabor Farms’ radish patch, about a mile south of the Salinas River, represent the cutting edge of change, a revolution in how America pulls food from the land.
For starters, the young men on their knees are working alongside technology unseen even 10 years ago. Crouched behind what looks like a tractor retrofitted with a packing plant, they place bunches of radishes on a conveyor belt within arm’s reach, which carries them through a cold wash and delivers them to be packed into crates and delivered for distribution in a refrigerated truck.
The other change is more subtle, but no less revolutionary. None of the workers are in the United States illegally.
are not coming in the numbers they once did.
There are a variety of reasons: The aging of Mexico’s population slimmed the cohort of potential migrants. Mexico’s relative stability after the financial crises of the 1980s and 1990s reduced the pressures for them to leave, while the collapse of the housing bubble in the United States slashed demand for their work north of the border. Stricter border enforcement by the United States, notably during the Trump administration, has further dented the flow.

As a consequence, the total population of unauthorized immigrants in the United States peaked in 2007 and has declined slightly since then. California felt it first. From 2010 to 2018, the unauthorized immigrant population in the state declined by some 10 percent, to 2.6 million. And the dwindling flow sharply reduced the supply of young workers to till fields and harvest crops on the cheap.
The state reports that from 2010 to 2020, the average number of workers on California farms declined to 150,000 from 170,000. The number of undocumented immigrant workers declined even faster. The Labor Department’s most recent National Agricultural Workers Survey reports that in 2017 and 2018, unauthorized immigrants accounted for only 36 percent of crop workers hired by California farms. That was down from 66 percent, according to the surveys performed 10 years earlier.
The immigrant work force has also aged. In 2017 and 2018, the average crop worker hired locally on a California farm was 43, according to the survey, eight years older than in the surveys performed from 2007 to 2009. The share of workers under the age of 25 dropped to 7 percent from a quarter.
