Consider a worker with a toothache whose shift overlaps the nearest health center's hours. If the worker lacks a reliable ride or paid leave, getting care may mean losing wages. A mobile program can plan evening stops near where workers live.
Farmworkers go without health care because the system is built around a schedule, a transportation model, a language, and a payment structure that do not match their lives. Most of those barriers are design problems. A program can design around them.
Half of hired crop workers have no insurance
Coverage is the first gap. A KFF analysis of the 2022 National Agricultural Workers Survey found 53% of hired crop workers were uninsured, compared with 10% of all nonelderly adults. The rate varies sharply by immigration status: 26% of citizens, 41% of noncitizens with work authorization, and 77% of noncitizens without it.
Employer coverage is rare in crop work, and Medicaid eligibility rules exclude many immigrants. Income is low as well. KFF found 19% of agricultural workers live below the federal poverty level, nearly four times the rate for all workers. For a program, this means the payer mix may lean heavily on sliding fee collections and grants. Health centers must maintain a sliding fee discount program for eligible patients. Current eligibility rules, including rules affecting some immigrants, should be reviewed with counsel before making promises about who can receive federally funded services.
The workday runs over clinic hours
Field work starts early and runs long, with few breaks and almost no paid sick leave. Harvest weeks can stretch to six or seven days. A weekday appointment means lost wages, and many workers fear it means a lost job.
This is the barrier mobile programs answer most directly. Evening clinics, weekend clinics, and stops timed to shift change can let a worker get care without giving up pay. For a fixed-site example of after-work hours, ReGenesis Health Care in South Carolina lists an Agricultural Farm Worker Clinic on Tuesday and Thursday evenings.
Getting to a clinic depends on transportation
Many farmworkers do not drive themselves. In the 2017-2018 National Agricultural Workers Survey report, about 69% drove to work. The rest relied on rides from others, including paid rides and group transportation. Guest workers on H-2A visas rely on employer-provided transportation, which federal rules require between housing and the work site. Those rides go to the field, and the clinic is usually not on the route.
Rural distance compounds the problem. A clinic 30 miles away can be unreachable for someone without a car, especially after a long shift. A mobile clinic at the housing site removes that trip.
Language goes beyond English and Spanish
Most hired crop workers are Hispanic (73% in the KFF analysis). Programs should ask local workers and community partners which languages patients prefer, then arrange qualified interpretation. Spanish-speaking staff may be important, but Spanish alone will not cover every community.
Spanish is not enough everywhere. In California, about a third of farmworkers come from Indigenous communities in southern Mexico, and many speak only Mixteco, Zapoteco, or Triqui. A patient who nods along to a Spanish explanation of a new medication may have understood little of it. Programs serving these communities need interpreters for Indigenous languages, and they need to know which languages their patients speak before the first clinic night.
Fear and uncertainty keep some people away
Immigration-related worry is a real factor in whether people seek care, and it has grown. In the KFF/New York Times 2025 Survey of Immigrants, the share of immigrant adults who skipped or postponed care rose from 22% in 2023 to 29% in 2025. Most cited cost or lack of coverage; about one in five cited immigration concerns. Half of immigrant adults said they worry that providers might share immigration status with enforcement officials.
Programs cannot change policy from the parking lot. They can be clear about what information they collect and why, protect it under HIPAA, train staff on how to respond to an enforcement visit, and keep the same trusted faces on the route. Our post on earning trust in farmworker communities covers those practices in more detail.
Chronic conditions go unmanaged
The barriers above add up to untreated disease. Half of agricultural workers in the KFF analysis (51%) had been told they have a chronic condition, and 21% could not get care they needed in the past year. Diabetes is especially common in some regions. A study of NAWS data from 2013 to 2016 found diabetes prevalence among Southwest farmworkers was nearly double that in other regions.
Seasonal moves interrupt treatment even for patients who do get diagnosed. Our post on chronic disease care for farmworkers who move with the seasons covers how mobile teams keep care going across a migration.
What this means for program design
Each barrier points to a design choice:
- For uninsured patients, a sliding fee scale, enrollment help for those who qualify, and braided grant funding
- For long work hours, evening, weekend, and shift-change clinics
- For transportation, stops at housing, camps, and packing sheds
- For language, bilingual staff and Indigenous-language interpreters
- For trust, promotores, a dedicated and consistent crew, and clear privacy practices
- For seasonal moves, records in the patient's hands and bridge prescriptions

Quick answers
What percentage of farmworkers are uninsured?
About 53% of hired crop workers were uninsured in 2022, according to KFF's analysis of the National Agricultural Workers Survey. The rate reaches 77% among noncitizens without work authorization.
Do farmworkers speak Spanish?
Most do, but not all. About a third of California farmworkers come from Indigenous communities in southern Mexico, and many speak only an Indigenous language such as Mixteco, Zapoteco, or Triqui.
