Estimating minimum labor demand (MLD) for hand-harvest farmworkers in New York State using crop production data yielded higher population estimates than the Department of Labor (DOL) figures. This suggests the DOL may significantly underestimate the farmworker population.

Area of Science:

  • Agricultural Economics
  • Labor Studies
  • Public Health

Background:

  • Accurate population estimates for hand-harvest farmworkers are crucial for assessing health needs and services.
  • New York State's Department of Labor (DOL) is the primary public source for farmworker population data.
  • Published crop production data offer an alternative avenue for estimating minimum labor demand (MLD).

Purpose of the Study:

  • To develop a method for estimating MLD for hand-harvested crops in New York State (NYS).
  • To compare MLD estimates derived from production data with existing DOL estimates.
  • To identify crop types where discrepancies between estimation methods are most pronounced.

Main Methods:

  • Crops were categorized into four strata: below ground, ground, bush/vine, and orchard.

  • MLD was calculated by dividing total annual harvest hours per crop stratum by hours worked per worker-season.
  • Data imputation was used for missing harvest acreage in 21% of county-crop combinations.

    • Main Results:

    • The total MLD estimate across all strata was 14,121 worker-seasons, significantly higher than the DOL estimate of 8,230.
    • The largest discrepancies were observed in ground crops, where DOL estimates were only 28% of the MLD estimate.
    • Estimates for orchard crops showed the closest agreement, with DOL figures at 109% of the MLD estimate.

    Conclusions:

    • Publicly available crop production data can be effectively used to estimate MLD for hand-harvest farmworkers.
    • The DOL may substantially underestimate the size of the hand-harvest farmworker population in NYS.
    • Future research should include county-level farm surveys to refine MLD estimation factors and improve accuracy.
