In 2012, when employment in California agriculture (NAICS 11) averaged 395,400, farm employers reported 802,600 unique Social Security numbers to the Employment Development Department, suggesting two unique workers per average job. Almost 675,000 farm workers had their maximum earnings with an identifiable farm employer in one county. Four counties, Kern, Fresno, Monterey, and Tulare, included almost half of these “primary farm workers.” In each of these counties, crop support (mostly labor contractors) employed the most workers, followed by fruits and nuts in the San Joaquin Valley and vegetables in Monterey.
