description: &lt;p&gt;The &lt;em&gt;Annual Population Survey&lt;/em&gt; (APS) is a major survey series, which aims to provide data that can produce reliable estimates at the local authority level. Key topics covered in the survey include education, employment, health and ethnicity. The APS comprises key variables from the &lt;em&gt;Labour Force Survey&lt;/em&gt; (LFS), all its associated LFS boosts and the APS boost. 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, the survey provides estimates for a range of indicators down to Local Education Authority (LEA) level across the United Kingdom.&lt;/p&gt;&lt;p&gt;For further detailed information about methodology, users should consult the &lt;em&gt;Labour Force Survey User Guide&lt;/em&gt;, included with the APS documentation. For variable and value labelling and coding frames that are not included either in the data or in the current APS documentation, users are advised to consult the latest versions of the LFS User Guides, which are available from the ONS &lt;a title="Labour Force Survey - User Guidance" href="https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/employmentandemployeetypes/methodologies/labourforcesurveyuserguidance" target="_blank" rel="noopener"&gt;Labour Force Survey - User Guidance&lt;/a&gt; webpages.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Occupation data for 2021 and 2022&lt;br&gt;&lt;/strong&gt;The ONS has 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. The affected datasets have now been updated. Further information can be found in the ONS article published on 11 July 2023: &lt;a title="Revision of miscoded occupational data in the ONS Labour Force Survey, UK: January 2021 to September 2022" href="https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/employmentandemployeetypes/articles/revisionofmiscodedoccupationaldataintheonslabourforcesurveyuk/january2021toseptember2022"&gt;Revision of miscoded occupational data in the ONS Labour Force Survey, UK: January 2021 to September 2022&lt;/a&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;APS Well-Being Datasets&lt;/strong&gt;&lt;br&gt;From 2012-2015, the ONS published separate APS datasets aimed at providing initial estimates of subjective well-being, based on the &lt;em&gt;Integrated Household Survey&lt;/em&gt;. In 2015 these were discontinued. A separate set of well-being variables and a corresponding weighting variable have been added to the April-March APS person datasets from A11M12 onwards. Further information on the transition can be found in the &lt;a title="Personal well-being in the UK: 2015 to 2016" href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/bulletins/measuringnationalwellbeing/2015to2016" target="_blank" rel="noopener"&gt;Personal well-being in the UK: 2015 to 2016&lt;/a&gt; article on the ONS website.&lt;br&gt;&lt;br&gt;&lt;strong&gt;APS disability variables&lt;br&gt;&lt;/strong&gt;Over time, there have been some updates to disability variables in the APS. An article explaining the quality assurance investigations on these variables that have been conducted so far is available on the &lt;a href="https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/employmentandemployeetypes/methodologies/analysisofthediscontinuityinthelabourforcesurveydisabilitydataapriltojune2017tojulytoseptember2017" target="_blank" rel="noopener"&gt;ONS Methodology&lt;/a&gt; webpage. &lt;/p&gt;&lt;div&gt;&lt;strong&gt;End User Licence and Secure Access APS data&lt;br&gt;&lt;/strong&gt;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 Secure Access version. The EUL version includes Government Office Region geography, banded age, 3-digit SOC and industry sector for main, second and last job. The Secure Access version contains more detailed variables relating to:&lt;/div&gt;&lt;ul&gt;
&lt;li&gt;age: 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&lt;/li&gt;
&lt;li&gt;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&lt;/li&gt;
&lt;li&gt;nationality and country of origin&lt;/li&gt;
&lt;li&gt;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&lt;/li&gt;
&lt;li&gt;health: including main health problem, and current and past health problems&lt;/li&gt;
&lt;li&gt;education and apprenticeship: including numbers and subjects of various qualifications and variables concerning apprenticeships&lt;/li&gt;
&lt;li&gt;industry: including industry, industry class and industry group for main, second and last job, and industry made redundant from&lt;/li&gt;
&lt;li&gt;occupation: including 4-digit Standard Occupational Classification (SOC) for main, second and last job and job made redundant from&lt;/li&gt;
&lt;li&gt;system variables: including week number when interview took place and number of households at address&lt;/li&gt;
&lt;/ul&gt;&lt;p&gt;





&lt;/p&gt;&lt;p&gt;The Secure Access data have more restrictive access conditions than those made available under the standard EUL. Prospective users will need to gain ONS Accredited Researcher status, complete an extra application form and demonstrate to the data owners exactly why they need access to the additional variables. Users are strongly advised to first obtain the standard EUL version of the data to see if they are sufficient for their research requirements.&lt;/p&gt;&lt;p&gt;&lt;/p&gt; &lt;p&gt;&lt;span style="font-weight: bold;"&gt;Latest edition information&lt;/span&gt;&lt;/p&gt;&lt;p&gt;For the fourth edition (March 2024), the smoking variables CIGEVER, CIGNOW and CIGSMK16 were added to the dataset.&lt;/p&gt;
