Sampling procedure
MICRODATA SOURCE: Office of Population and Surveys for England and Wales
SAMPLE SIZE (person records): 495581.
SAMPLE DESIGN: Original data from which the sample was extracted is itself a systematic sample of every 10th household, selected during the data collection process, and that received the long form. The original data was then stratified by household type and sorted geographically. One in ten households was subsequently systematically excluded. Persons living in communal establishments or in households with more than nine residents were excluded. Finally, a 0.95% sample of households was extracted by selecting randomly 1-in-9 households from the remaining long form respondents. Individuals within communal establishments and those in households with more than nine residents were selected separately from data ordered by geography. No weighting was applied. NOTE: The sample excludes Northern Ireland. It includes England, Scotland and Wales.
Mode of data collection
Face-to-face [f2f]
Research instrument
Two questionnaires: a long form applied to ten percent of the poulation and a short form to the other ninety percent. Each of them collected information from all persons, private households, and persons absent from the household.

UNITS IDENTIFIED: - Dwellings: Yes - Vacant Units: No - Households: yes - Individuals: yes - Group quarters: Yes
UNIT DESCRIPTIONS: - Dwellings: no - Households: A household is either one person living alone, or a group of persons (who may or may not be related) living at the same address with common housekeeping. Persons staying temporarily with the household are included. A boarder having at least one meal a day with the household counts as a member of the household (breakfast counts as a meal for this purpose); but a lodger taking no meals with the main household counts as a separate one-person household, even if he shares kitchen and bathroom. A group of unrelated persons sharing a house or flat would count as one or as several households according to whether they maintained common housekeeping or provided their own meals separately. - Group quarters: Yes
Universe
All persons who spent census night of April 25/26 of 1971 in the household or joined the household on April 26th and who have not been included as present elsewhere; this comprises households, non-private establishments, on board a vessel, or elsewhere in the area of enumeration. In particular the enumerated population includes people who usually lived elsewhere, including abroad, but who were temporarily staying in the area on census night. Members of the armed forces and mercantile marine outside Great Britain on census night were excluded. Members of foreign or Commonwealth armed forces were included if present in the country on census night, but foreign and Commonwealth naval vessels, and the people on board them, were not enumerated.

Sampling procedure
MICRODATA SOURCE: Centre for Census and Survey Research
SAMPLE SIZE (person records): 1843525.
SAMPLE DESIGN: The sampling scheme for the household SAR (Sample of anonymised records) is a stratified simple random sampling, where the strata are EDs (Enumeration districts). Unlike 1991, there is no stratification within EDs. Random sampling is applied within each ED. The sampling scheme for the individual SAR follows the 1991 approach of drawing from the population excluding the household sample. Stratification is again by ED. The Individual SAR sampled both private and communal persons, unlike the household SAR which only sampled only households.

Population and Housing Census [hh/popcen]
Sampling procedure
MICRODATA SOURCE: Centre for Census and Survey Research
SAMPLE SIZE (person records): 541894.
SAMPLE DESIGN: All fully-coded household forms were ordered geographically with the lowest level the enumeration area. Households were then grouped into batches of 10 and one household selected at random from each batch. The two per cent Individual sample was then drawn from the remaining households. Individuals in the remaining households were stratified into groups of nine, and two individuals selected from each group at random. Individuals in communal establishments were stratified into groups of five and one individual selected at random from each group. NOTE: The sample excludes Northern Ireland. It includes England, Scotland and Wales. NOTE2: Many data items are not available for households with 12 or more persons, for confidentiality reasons. These cases are coded "not in universe" in the affected variables.
