About 5.7 million people lived in households affiliated with a farm business in 1990 compared with almost 4.6 million in the farm population as conventionally defined by place of residence. The economically defined group, called the farm entrepreneurial population, includes people who derive all or part of their livelihood from farm operations but do not necessarily live on a farm. This report analyzes census data on income, education, and other characteristics of the group identified by farm occupation and farm self-employment income criteria.
