description: &lt;p&gt;The &lt;em&gt;1970 British Cohort Study&lt;/em&gt; (BCS70) began in 1970 when data were collected about the births and families of babies born in the United Kingdom in one particular week in 1970. Since then, there have been nine further full data collection exercises in order to monitor the cohort members' health, education, social and economic circumstances. These took place when respondents were aged 5 in 1975, aged 10 in 1980, aged 16 in 1986, aged 26 in 1996, aged 30 in 1999-2000 (SN 5558), aged 34 in 2004-2005, aged 42 in 2012 and aged 46 in 2016-18. A range of sub-sample and supplementary surveys have also been conducted, and a separate dataset covering response to BCS70 over all waves is available under SN 5641, &lt;em&gt;1970 British Cohort Study Response Dataset, 1970-2012.&lt;/em&gt;&lt;/p&gt; &lt;p&gt;Further information about the BCS70 and may be found on the &lt;a title="Centre for Longitudinal Studies" href="http://www.cls.ioe.ac.uk/"&gt;Centre for Longitudinal Studies&lt;/a&gt; website. As well as BCS70, the CLS now also conducts the NCDS series. &lt;br&gt; &lt;br&gt; &lt;em&gt;How to access genetic and/or bio-medical sample data from a range of longitudinal surveys:&lt;/em&gt;&lt;br&gt; A useful overview of the governance routes for applying for genetic and bio-medical sample data, which are not available through the UK Data Service, can be found at &lt;a title="Governance of data and sample access" href="http://www.metadac.ac.uk/data-access-through-metadac/"&gt;Governance of data and sample access&lt;/a&gt; on the METADAC (Managing Ethico-social, Technical and Administrative issues in Data Access) website.&lt;/p&gt; The &lt;i&gt;1&lt;/i&gt;&lt;span style="font-style: italic;"&gt;970 British Cohort Study: Age 42, Sweep 9, 2012&lt;/span&gt;, comprised two parts: a 'core' face-to-face interview and a paper self-completion questionnaire. The survey sought to update information gathered in previous surveys in order to explore the factors central to the formation and maintenance of adult identity in each of the following domains:&lt;ul&gt;&lt;li&gt;lifelong learning&lt;/li&gt;&lt;li&gt;relationships, parenting and housing&lt;/li&gt;&lt;li&gt;employment and income&lt;/li&gt;&lt;li&gt;health and health behaviour&lt;/li&gt;&lt;li&gt;citizenship and values.&lt;/li&gt;&lt;/ul&gt;The 2012 follow-up also included questions on a number of new topics that have either not previously been covered at all or not covered in adulthood, including: housing costs and housing equity; sexuality; cultural consumption - books, television, newspapers; religious beliefs - belief in God, belief in the after life; experience of the menopause; fertility intentions; diet - consumption of ready-meals, convenience foods, take-aways and home-cooked meals; sleep.&lt;br&gt; &lt;br&gt; For the second edition (June 2016) a small number of primary identifiers (BCSID) have been changed to realign them to previous sweeps of data. See the documentation for full details of the work done.&lt;br&gt; &lt;br&gt;
