Answer:
A household employment status is in most cases the main factor that determines whether that household is self sufficient or not.
Step-by-step explanation:
Most people in the world live off their work, that means that they need a wage to fufill their needs, and in order to obtain that wage, they need employment. This is why the presence or not of employment in a household is such an important factor: it is safe to assume that without employment most households are not self-sufficient, unless that particular household has other sources of income, like rents, dividends, and so on.
