This class covers the same job types as the “Self-Employed” class of worker, but Extended Proprietor jobs represent miscellaneous labor income for persons who do not consider it a primary job. Extended Proprietor jobs include minor or underreported self-employment, investments trusts and partnerships, certain farms, and tax-exempt nonprofit cooperatives. This class is normally only used for Input-Output purposes, since investments and partnerships in particular will be overrepresented in certain sectors.
