The person or persons occupying a housing unit. Counts of households, householders, and occupied-housing units are always identical in complete-count tabulations. In sample tables, the numbers may not always be the same because of differences in weighting sample data.

Net money income (gross receipts minus business expenses) received from an unincorporated nonfarm business, professional enterprise, or partnership in which the person was engaged on his or her own account. Gross receipts include the value of all goods sold and services rendered. Business expenses include cost of goods purchased, rent, heat, light, power, depreciation charges, wages and salaries paid, business taxes (not personal income taxes), etc. The so-called "salary" that some owners of unincorporated businesses pay themselves is included here. On the other hand, income received for working for an incorporated business, even though the person may own the business, is counted under wage or salary income.
