Census Access Project: This is the ONS initiative to make Census data freely available to all, primarily via the National Statistics website and the Neighbourhood Statistics website .
Census Area Statistics: Census tables available for Output Areas upwards, particularly the 2-way tables relating one topic to another (e.g. Ethnic Group by Age). Term can be used loosely to include Univariate Tables as well.
Census Coverage Survey: Large survey (320000 households) carried out after the Census to establish extent of Census non-response.
Enumeration District: This is the patch covered by an individual enumerator during the Census fieldwork in April 2001. Unlike the 1991 Census, results are not published for Enumeration Districts. The smallest area for which tables of results are now published is the Output Area.
Headcounts: Total number of males, females and households. Available at Unit Postcode level upwards.
Key Statistics: Set of simple Census tables each telling us about one topic (such as Economic Activity, or Tenure, or Ethnic Group). Available for Output Areas upwards.
National Statistics: Shorthand term for 'Office for National Statistics' (ONS), and/or the statistics they publish. See the National Statistics website for Census results for larger areas, such as Districts.
Neighbourhood Statistics: Small-area statistics from the ONS. The Neighbourhood Statistics website includes Key Statistics and the simplest kind of Census Area Statistics, for Output Areas upwards.
Occupancy Rating: Measure of overcrowding, based on how many rooms are 'needed' given the number of household residents and the relationships between them. E.g., a value of -1 implies there is one room too few.
One Number Census (ONC): The name of the new methodology used in 2001 to:-
- estimate Census non-response, and
- build an allowance for it into all the published figures.
ONS (Office for National Statistics): Government agency which carries out the Census in England and Wales.
Origin-Destination Statistics: Outputs relating to two places, concerning the flow of people from one to the other. This flow may take the form of migration (Special Migration Statistics) or commuting (Special Workplace Statistics).
Output Area: This is the smallest area for which tables of results are published in the 2001 Census. Output Areas have an average of 125 households each (smaller than the Enumeration Districts used in previous Censuses). They fit into Wards, and are made up of entire Unit Postcodes wherever possible. Tameside has 725 Output Areas.
SASPAC: Computer package for analysing the Census.
Special Migration Statistics: Origin-Destination statistics about migration, telling us how many people had moved from one place (ward, district etc) to another in the year before the Census.
Special Workplace Statistics: Origin-Destination statistics about migration, telling us how many people commute from one place (ward, district etc) to another.
Standard Area Statistics: Umbrella term for Key Statistics, Standard Tables, Theme Tables, Census Area Statistics and Univariate Tables.
Standard Tables: These are the detailed 2-way tables for Wards or bigger areas, relating one topic to another (e.g. Ethnic Group by Age).
SuperTable: Computer package for analysing the Census.
Theme Tables: Tables relating a main theme to several other issues. E.g. the 'Theme Table on Religion' gives breakdowns for each religion by age, sex, economic activity, tenure, accommodation type, qualifications, limiting long-term illness and general health. Supplied for Wards and above, and in a less detailed version for Output Areas.
Unit Postcode: Complete postcode, e.g. OL6 6DL. The only data available at this level is Headcounts.
Univariate Tables: Tables that each deal with only one topic - e.g. Ethnic Group or Age or Economic Activity. Supplied for Output Areas and above.
Wards: The wards for which 2001 Census data is published have been superseded by a boundary change in June 2004. Census results for the new wards can only be approximated by combining results for Output Areas.
