Primary earnerとは 意味・読み方・使い方

When a private household (110-4) contains several persons they are called members of the household ¹ and one of them will be the head of the household ² . There is no universally accepted rule as to who is considered the head of the household; in some cases it may be the principal earner ³. On most census schedules there appears a question dealing with the relationship ⁴ (114-3*) of members of the household to its head. This enables a distinction to be made between different groups in composite households ⁵ or complex households ⁵ which contain members of more than one biological family or nuclear family (113-1). A composite or complex household can be disaggregated into several nuclei ⁶, including a primary nucleus ⁷ and secondary nuclei ⁸. The nuclei are more commonly called families (112-1). Household size ¹¹ denotes the number of persons included in the household.

• 2. The term householder is sometimes used to refer to the head of the household. The term headship is frequently encountered, as in headship ratio, the ratio of the number of heads of households by age, sex or other characteristics to the corresponding categories of population.
• 6. The nucleus is also called a conjugal family unit.
