1970 British Cohort Study: Sweeps 3-9, 1980-2012, Townsend Index (LSOA) Linked Data: Secure Access

<p>The <span style="font-style: italic;">1970 British Cohort Study</span> (BCS70) is a longitudinal birth cohort study, following a nationally representative sample of over 17,000 people born in England, Scotland and Wales in a single week of 1970. Cohort members have been surveyed throughout their childhood and adult lives, mapping their individual trajectories and creating a unique resource for researchers. It is one of very few longitudinal studies following people of this generation anywhere in the world.<br><br>Since 1970, cohort members have been surveyed at ages 5, 10, 16, 26, 30, 34, 38, 42, 46, and 51. Featuring a range of objective measures and rich self-reported data, BCS70 covers an incredible amount of ground and can be used in research on many topics. Evidence from BCS70 has illuminated important issues for our society across five decades. Key findings include how reading for pleasure matters for children's cognitive development, why grammar schools have not reduced social inequalities, and how childhood experiences can impact on mental health in mid-life. Every day researchers from across the scientific community are using this important study to make new connections and discoveries.<br><br>BCS70 is run by the <a href="https://cls.ucl.ac.uk/cls-studies/1970-british-cohort-study/" target="_blank" style="background-color: rgb(255, 255, 255);">Centre for Longitudinal Studies</a> (CLS), a research centre in the UCL Institute of Education, which is part of University College London.

Derived summary scores have been created that combine the estimated effects of many different genes on a specific trait or characteristic, such as a person's risk of Alzheimer's disease, asthma, substance abuse, or mental health disorders, for example. These polygenic scores can be combined with existing survey data to offer a more nuanced understanding of how cohort members' outcomes may be shaped.<br><br><span style="font-style: italic;">Secure Access datasets<br></span>Secure Access versions of BCS70 have more restrictive access conditions than versions available under the standard Safeguarded Licence.<br><br></p> <div>The <span style="font-style: italic;">1970 British Cohort Study: Sweeps 3-9, 1980-2012, Townsend Index (LSOA) Linked Data: Secure Access </span>study includes the Towsend Index of Deprivation data for Sweeps 3-9 of the BCS70, as well as the variables needed to construct these.<br><br><span style="font-weight: bold;">International Data Access Network (IDAN)</span><br>These data are now available to researchers based outside the UK.
