For statistical purposes in the United Kingdom, 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 meala day or share the living accommodation, that is, a living room or sitting room". The introduction of legislation to control houses of multiple occupation in the UK Housing Act required a tighter definition of a single household. People can be considered a household if they are related: full- or half-blood, foster, step-parent/child, in-laws, a married couple or unmarried but "living as ...". The United States Census definition also hinges on "separate living quarters": "those in which the occupants live and eat separately from any other persons in the building." According to the U.S. census, a householder is the "person in whose name the housing unit is owned or rented "; if no person qualifies, any adult resident of a housing unit is considered a householder. The U.S. government formerly used "head of the household" and "head of the family", but those terms were replaced with "householder" in 1980. In the census definition of a household, it On July 15, 1998, Statistics Canada said: "A household is generally defined as being composed of a person or group of persons who co-reside in, or occupy, a dwelling."
Economic definition
Although a one-income-stream economic theory simplifies modeling, it does not necessarily reflect reality. Many, if not most, households have several income-earning members. Most economic models do not equate households and traditional families, and there is not always a one-to-one relationship between households and families.
Social definitions
In social work, a household is defined similarly: a residential group in which housework is divided and performed by householders. Care may be delivered by one householder to another, depending upon their respective needs, abilities, and disabilities. Household composition may affect life and health expectations and outcomes for its members. Eligibility for community services and welfare benefits may depend upon household composition. In sociology, household work strategy is the division of labour among members of a household. Household work strategies vary over the life cycle as household members age, or with the economic environment; they may be imposed by one person, or be decided collectively. Feminism examines how gender roles affect the division of labour in households. In The Second Shift and The Time Bind, sociologist Arlie Russell Hochschild presents evidence that in two-career couples men and women spend about equal amounts of time working; however, women spend more time on housework. Cathy Young says that in some cases, women may prevent the equal participation of men in housework and parenting.
Models
Household models in the English-speaking world include traditional and blended families, shared housing, and group homes for people with support needs. Other models which may meet definitions of a household include boarding houses, houses in multiple occupation, and single room occupancy.
History
In feudal or aristocratic societies, a household may include servants or retainers who derive their income from the household's principal income.
A 1961–62 National Housing Institute survey estimated that 13.8 percent of Belgian dwellings were unfit and incapable of improvement. A further 19.5 percent were unfit but had the potential to be improved, and 54 percent were considered suitable for modern living standards. Seventy-four percent of dwellings lacked a shower or bath, 19 percent had inadequate sewage disposal, and 3.6 percent lacked a drinking-water supply; 36.8 percent had an indoor water closet. According to a 1964 study, 13 percent of Belgium's housing consisted of slums.
France
Between 1954 and 1973, the percentage of French homes with a shower or bath increased from 10 to 65 percent. During that period, the percentage of homes without flush toilets fell from 73 to 30 percent; homes without running water fell from 42 to 3.4 percent. A 1948 law permitted gradual, long-term rent increases for existing flats on the condition that part of the money was spent on repairs. According to John Ardagh, the law, "vigorously applied, was partly successful in its twofold aim: to encourage both repairs and new building."
United Kingdom
After World War II, a large percentage of British housing was single-family housing. Seventy-eight percent of housing in 1961 consisted of single-family homes, compared to 56 percent in the Netherlands, 49 percent in West Germany and 32 percent in France. In England and Wales in 1964, 6.6 percent of housing units had two or fewer rooms; 5.8 percent had seven or more rooms, 15.2 percent had six rooms, 35.1 percent had five rooms, 26.3 percent had four rooms, and 11.1 percent had three rooms. These figures included kitchens when they were used for eating meals. Fifty percent of 1964 housing had three bedrooms; 1.9 percent had five or more bedrooms, 6.2 percent had four bedrooms, 10.5 percent had one bedroom or none, and 31.3 percent had two bedrooms. A 1960 social survey estimated that 0.6 percent of households in England and Wales exceeded the statutory overcrowding standard; the 1964 percentage was 0.5 percent. In 1964, 6.9 of all households exceeded one person per room. The 1960 figure was 11 percent, with 1.75 percent having two or more bedrooms below the standard and 9.25 percent having one bedroom below the standard. This declined slightly by 1964 to 9.4 percent of households below the standard, with 8.1 percent having one bedroom below the standard and 1.3 percent having two bedrooms or more below the standard. According to local authorities in 1965, five percent of the housing stock in England and Wales was unfit for habitation.
U.S. and Canada
Housing conditions improved in Canada and the U.S. after World War II. In the U.S., 35.4 percent of all 1950 dwellings did not have complete plumbing facilities; the figure fell to 16.8 percent in 1960 and 8.4 percent in 1968. In Canada from 1951 to 1971, the percentage of dwellings with a bath or shower increased from 60.8 to 93.4 percent; the percentage of dwellings with hot and cold running water increased from 56.9 to 93.5 percent. In the United States from 1950 to 1974, the percentage of housing without full plumbing fell from 34 to three percent; during that period, the percentage of housing stock considered dilapidated fell from nine percent to less than four.
