description: &lt;p&gt;The &lt;i&gt;Annual Population Survey&lt;/i&gt; (APS) household datasets are produced annually and are available from 2004 (Special Licence) and 2006 (End User Licence). They allow production of family and household labour market statistics at local areas and for small sub-groups of the population across the UK. The household data comprise key variables from the &lt;i&gt;Labour Force Survey&lt;/i&gt; (LFS) and the APS 'person' datasets. The APS household datasets include all the variables on the LFS and APS person datasets, except for the income variables. They also include key family and household-level derived variables. These variables allow for an analysis of the combined economic activity status of the family or household. In addition, they also include more detailed geographical, industry, occupation, health and age variables.&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;br&gt;&lt;br&gt;&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. 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;br&gt;&lt;br&gt;
&lt;b&gt;End User Licence and Secure Access APS data&lt;/b&gt;&lt;br&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;/p&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;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. For the second edition (September 2023), SOC variables NSECM20, NSECMJ20, SC20LMJ, &lt;div&gt;SC20LMN, SC20MMJ, SC20MMN, SC20SMJ and SC20SMN were replaced with revised versions. Further information on the SOC revisions 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" style="background-color: rgb(255, 255, 255); transition: all 0.2s linear 0s;"&gt;Revision of miscoded occupational data in the ONS Labour Force Survey, UK: January 2021 to September 2022&lt;/a&gt;.&lt;/div&gt;
