What is the prevalence of disability within the U.S. farm and ranch population?

Deboy et al. (2008) conducted research to estimate the prevalence of disability within the U.S. farm and ranch population and concluded that between 1.04 million and 2.23 million individuals within the agricultural population were impacted by disability. The primary reasons cited for the inability to provide a more precise population size included the lack of consistent survey methodologies and definitions used for agricultural workers. Other studies have indicated that between 15 and 20 percent of the adult farm and ranch workforce has a physical disability that prevents them from completing certain work-related tasks.
