5. Does everyone that lives in this dwelling depend on a single food source, that is to say, is part of a single household?
What is a household? A person or group of people (family or not) that generally live under the same roof and provide for food needs in a communal way.
Generally the members of a household tend to pool their income, set up a common budget, establish shared use of durable and nondurable resources, etc. which give the members of the household similar characteristics.
"To depend on the same food source" constitutes a main discriminatory factor. In the case of which all the occupants of the selected dwelling fulfill the previous criteria, code 1 is circled, in case of the contrary, you will investigate how many groups of people are sharing food sources in the house and note what corresponds.
Renters are not part of the principal household, they form a separate household, because they don't participate in a common source but rather pay for a service.
If in the broad majority of the cases a household consists of a head and family members, you can find one-person households, that is to say, constituted by only one person.

It's important to clarify that the population of interest for the Extended National Survey of Households is private households, which is defined in the paragraphs above, explicitly excluding collective households. That's to say people who share a dwelling for reasons of study (student residences), health (sanatoriums, hospitals, etc.), penitentiaries (prisons, etc.), religion (convents, etc.), etc.
