1991 resident population  The count of all persons recorded as resident in households in an area, even if they were elsewhere on Census night, plus residents in communal establishments who were present in the establishment on Census night. In contrast to 2001, students and schoolchildren are counted as resident at their vacation address. Persons from wholly absent households are included.

In 1991 there was also a count of the population present in an area on Census night (Persons Present Population Base 1991). This information is not available for 2001.

Communal Establishment  A communal establishment is defined as an establishment providing managed residential accommodation. Managed means full-time or part-time supervision of the accommodation. 

In most cases (for example, prisons, large hospitals, hotels) communal establishments can be easily identified. However, difficulties can arise with small hotels, guesthouses and sheltered accommodation. Special rules apply in these cases:

Small hotels and guesthouses are treated as communal establishments if they have the capacity to have 10 or more guests, excluding the owner/manager and his/her family. 

Sheltered housing is treated as a communal establishment if less than half the residents possess their own facilities for cooking. If half or more possess their own facilities for cooking (regardless of use) the whole establishment is treated as separate households.

h

Communal Establishment Resident  The basic 'Household Resident' definition applies when determining whether someone is a resident of a communal establishment. Where clarification is needed, a resident is any person who has been living, or intends to live, in the establishment for six months or more. People visiting the establishment on Census day who do not have a usual address elsewhere are also classified as a resident. Usual residents absent on Census day were left a Census form for statutory completion on their return to the establishment.

In some tables 'Residents' excludes members of staff and their families.

Community Background  This variable is applicable in Northern Ireland only. It identifies a person's current religious group, if any, or the religious group brought up in for people who do not regard themselves as belonging to any religion.

The four categories of Community Background are:-Catholic; Protestant; Other Christian and Christian-related; Other Religions and Philosophies; and None.

The category 'Catholic' includes those respondents who gave their religion as Roman Catholic, Catholic Apostolic Church, Ukrainian Catholic, Greek Catholic, Palmarian Catholic or Catholic.

Responses have been categorised as 'Protestant, Other Christian and Christian Related' or 'Other Religions and Philosophies' on the basis of the best available information, although it is acknowledged that the categorisation of some of the smaller religions is open to interpretation.

Country of Birth  There are five tick box responses to the country of birth question: one each for the four parts of the UK and one for the Republic of Ireland. Where there is no applicable tick box, people were asked to write in the present name of their country of birth. The written responses are coded using the ONS Geography Classification of Countries. Countries are classified in output according to the geographical position rather than politics. For example, the Canary Islands are classified as North Africa rather than Western Europe even though they belong to Spain.

Dependent Child  A dependent child is a person aged 0-15 in a household (whether or not in a family) or aged 16-18 in full-time education and living in a family with his or her parent(s). This is a change from the 1991 definition which was a person aged 0-15 in a household or a person aged 16-18, never married, in full-time education and economically inactive. The revised 2001 definition has been agreed following consultation with users. An 'adult' in a household is any person who is not a dependent child.

Family Reference Person  In a lone parent family, the Family Reference Person (FRP) is taken to be the lone parent in a lone parent family. In a couple family, the FRP is chosen from the two people in the couple on the basis of their economic activity (in the priority order; full-time job, part-time job, unemployed, retired, other). If both people have the same economic activity, the FRP is identified as the elder of the two or, if they are the same age, the first member of the couple on the form.

Full-time student  A full-time student is a person of any age who has indicated that they are a schoolchild or student in full-time education.

Full-time students and schoolchildren who are economically active are identified separately in the economic activity tables. They are not included in the other categories of economically active such as 'employees' or 'unemployed'. 

In tables on occupation and industry, where students are not identified separately, they are included under the appropriate occupation or industry.

In the National Statistics Socio-economic Classification all full-time students are recorded in the 'full-time students' category regardless of whether they are economically active or not.

The economic activity questions are only asked of people aged 16-74.

Highest Level of Qualification  In England and Wales, the highest level of qualification is derived from responses to both the qualifications question and the professional qualification question. For Scotland and Northern Ireland, it is based on the qualifications question. As the levels are derived from different questions they are not (or are only approximately) equivalent.

Household composition  Households consisting of one family and no other people are classified according to the type of family and the number of dependent children. Other households are classified by the number of dependent children or whether all student or all pensioner.An alternative classification defines households by the age of the people in it. It takes no account of the relationships between people.

Household deprivation  This term is used in one univariate table. The classification is not related to the DTLR Index of Multiple Deprivation nor the NISRA Measures of Deprivation for Northern Ireland. It is one of the Alternative Household Classifications resulting from an ESRC project completed in 2001.

There are four dimensions of household deprivation defined. A household is 'deprived' in the following dimension(s) if:

Employment: Any member of the household aged 16-74 who is not a full-time student is either unemployed or permanently sick.

Education: No member of the household aged 16 to pensionable age has at least 5 GCSEs (grade A-C) or equivalent AND no member of the household aged 16-18 is in full-time education. [NB. For Scotland the education level is at least one Standard Grade or equivalent which is a lower level.]

Health and disability: Any member of the household has general health 'not good' in the year before Census or has a limiting long-term illness.

Housing: The household's accommodation is either overcrowded (occupancy indicator is -1 or less), OR is in a shared dwelling OR does not have sole use of bath/shower and toilet OR has no central heating.

Household Reference Person  The concept of Household Reference Person (HRP) is new in 2001 output. It replaces Head of Household used in 1991. For a person living alone, it follows that this person is the HRP. If the household contains only one family (with or without ungrouped individuals) the HRP is the same as the Family Reference Person (FRP). If there is more than one family in the household, the HRP is chosen from among the FRPs using the same criteria as for choosing the FRP (economic activity, then age, then order on the form). If there is no family, the HRP is chosen from the individuals using the same criteria. In 1991, the Head of Household was taken as the first person on the form unless that person was aged under 16 or was not usually resident in the household.

Household Resident  A household resident is any person who usually lives at the address, or who has no other usual address. For people with more than one address (e.g. Armed Forces personnel, people who work away from home) the usual address is where the person spends the majority of his/her time, unless they have a spouse or partner at another address. In the latter instance, the usual address is where the person's family resides. Students and schoolchildren studying away from the family home are treated as resident at their term-time address.
