Annual Population Survey Two-Year Longitudinal Dataset, January 2020 - December 2021
Bibliographic record
Abstract
<p>The&nbsp;<i>Annual Population Survey</i>&nbsp;(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<a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000026">&nbsp;</a><i><a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=2000026">Labour Force Survey</a></i>&nbsp;(LFS), all its associated LFS boosts and the APS boost.</p><p>The APS allows for analysis to be carried out on detailed subgroups and below regional level. In recent years (particularly with the sample size of the LFS 5 quarter dataset reducing) there has been some interest in producing a two year APS longitudinal dataset to look at any trends that may occur over a year. The&nbsp;APS Two-Year Longitudinal Datasets, covering 2012/13 onwards, have been deposited as a result of this work. <a href="https://beta.ukdataservice.ac.uk/datacatalogue/series/series?id=200002#!/access-data">Person- and Household-level APS</a> datasets are also available.</p><p> </p><p>For further detailed information about methodology, users should consult the&nbsp;<i>Labour Force Survey User Guide</i>, included with the APS documentation.</p><p><span style="font-weight: bold;">Occupation data for 2021 and 2022 data files</span><br> </p><p>The ONS have identified an issue with the collection of some occupational data in 2021 and 2022 data files in a number of their surveys. While they estimate any impacts will be small overall, this will affect the accuracy of the breakdowns of some detailed (four-digit Standard Occupational Classification (SOC)) occupations, and data derived from them. None of ONS' headline statistics, other than those directly sourced from occupational data, are affected and you can continue to rely on their accuracy.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
