Which workers are excluded from jobs reports?

The monthly jobs report emphasizes that it reports on nonfarm payroll. Who exactly counts as a farm worker? Some farms have side businesses such as restaurants, how are those workers counted? Are there any other categories of workers besides farming that are intentionally not included in the report?

“It does not include farm workers, private household employees, or non-profit organization employees.”

“A farmworker is a hired agricultural worker on a farm that works for the farmers. However, in discussions relating to labor law application, the term “farmworker” is sometimes used more narrowly, applying only to a hired worker involved in agricultural production, including harvesting, i.e. not to a worker in other on-farm jobs, such as packing.”
