The household is the basic unit of analysis in many microeconomic and government models.
Most economic models do not address whether or not the members of a household are a family in the traditional sense.
For UK statistical purposes, a household is defined as "one person or a group of people who have the accommodation as their only or main residence and (for a group) either share at least one meal a day or share the living accommodation, that is, a living room or sitting room" (see National Statisticsarticle).
