Abstract:
The Annual Population Survey (APS) is a major survey series, which aims to provide data that can produce reliable estimates at local authority level. Key topics covered in the survey include education, employment, health and ethnicity. The APS comprises key variables from the Labour Force Survey (LFS) (held at the UK Data Archive (UKDA) under GN 33246), all its associated LFS boosts and the APS boost. Thus, the APS combines results from five different sources: the LFS (waves 1 and 5); the English Local Labour Force Survey (LLFS), the Welsh Labour Force Survey (WLFS), the Scottish Labour Force Survey (SLFS) and the Annual Population Survey Boost Sample (APS(B) - however, this ceased to exist at the end of December 2005, so APS data from January 2006 onwards will contain all the above data apart from APS(B)). Users should note that the LLFS, WLFS, SLFS and APS(B) are not held separately at the UKDA. For further detailed information about methodology, users should consult the Labour Force Survey User Guide, selected volumes of which have been included with the APS documentation for reference purposes (see 'Documentation' table below).

The APS aims to provide enhanced annual data for England, covering a target sample of at least 510 economically active persons for each Unitary Authority (UA)/Local Authority District (LAD) and at least 450 in each Greater London Borough. In combination with local LFS boost samples such as the WLFS and SLFS, the survey provides estimates for a range of indicators down to Local Education Authority (LEA) level across the United Kingdom.

End User Licence and Special Licence APS data
Users should note that there are two versions of each APS dataset. One is available under the standard End User Licence (EUL) agreement, and the other is a Special Licence (SL) version. The SL version contains more detailed variables relating to:

• age: including single year of age, year and month of birth, age completed full-time education and age obtained highest qualification, age of oldest dependent child and age of youngest dependent child
• family unit and household: including a number of variables concerning the number of dependent children in the family according to their ages, relationship to head of household and relationship to head of family
• nationality and country of origin
• geography: including county, unitary/local authority, place of work, Nomenclature of Territorial Units for Statistics 2 (NUTS2) and NUTS3 regions, and whether lives and works in same local authority district
• health: including main health problem, and current and past health problems
• education and apprenticeship: including numbers and subjects of various qualifications and variables concerning apprenticeships
• industry: including industry, industry class and industry group for main, second and last job, and industry made redundant from
• occupation: including 4-digit Standard Occupational Classification (SOC) for main, second and last job and job made redundant from
• system variables: including week number when interview took place and number of households at address

Coverage:
Dates of Fieldwork: July 2005-June 2006
Country: United Kingdom
Spatial Units: Government Office Regions (GORs);Unitary Authorities (England); Government Office Regions (GORs);Unitary Authorities (England); Local Authority Districts; Local Authority Districts
Observation Units: Individuals
Kind of Data: Numeric data; Individual (micro) level

Universe Sampled:
Location of Units of Observation:National
Population:Persons resident in the UK in private households, and young people living away from the parental home in student halls of residence or similar institutions during term time.

Methodology:
Time Dimensions: Repeated cross-sectional study
The survey has a panel element, in that the households at selected addresses are interviewed annually over four waves, in the same way as for the LFS boosts. They then leave the survey and are replaced by other households.
Sampling Procedures: Multi-stage stratified random sample
Number of Units: 365,016 cases
Method of Data Collection: Face-to-face interview; Telephone interview
Weighting: For later studies in the series, due to the removal of APS(B) cases, there is now a single weighting variable, PW06, for use with all variables. The weight has been rounded to be integer, in line with the LFS.
Data Sources: See the 'Abstract' section above for details of sources used.
