This dataset contains counts of live births for California as a whole based on information entered on birth certificates. Final counts are derived from static data and include out of state births to California residents, whereas provisional counts are derived from incomplete and dynamic data. Provisional counts are based on the records available when the data was retrieved and may not represent all births that occurred during the time period.

The final data tables include both births that occurred in California regardless of the place of residence (by occurrence) and births to California residents (by residence), whereas the provisional data table only includes births that occurred in California regardless of the place of residence (by occurrence). The data are reported as totals, as well as stratified by parent giving birth's age, parent giving birth's race-ethnicity, and birth place type. See temporal coverage for more information on which strata are available for which years.

Abstract copyright UK Data Service and data collection copyright owner.The 1970 British Cohort Study (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 sureveyed 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.Since 1970, cohort members have been surveyed at ages 5, 10, 16, 26, 30, 34, 38, 42 and 46. 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.BCS70 is run by the Centre for Longitudinal Studies (CLS), a research centre in the UCL Institute of Education, which is part of University College London.

The 1970 British Cohort Study: Age 16, Sweep 4 Arithmetic Test, 1986 includes data derived from an arithmetic test administrated in 1986, when cohort members were 16 years old. The test used was known as the APU Arithmetic Test and consisted of 60 questions. The test was included in the Student Test Book and cohort members recorded their answers on a machine-readable Student Score Form. Thirty minutes were allowed for completion of the test. 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.

The National Child Development Study (NCDS) is a continuing longitudinal study that seeks to follow the lives of all those living in Great Britain who were born in one particular week in 1958. The aim of the study is to improve understanding of the factors affecting human development over the whole lifespan.

The NCDS has its origins in the Perinatal Mortality Survey (PMS) (the original PMS study is held at the UK Data Archive under SN 2137). This study was sponsored by the National Birthday Trust Fund and designed to examine the social and obstetric factors associated with stillbirth and death in early infancy among the 17,000 children born in England, Scotland and Wales in that one week. Selected data from the PMS form NCDS sweep 0, held alongside NCDS sweeps 1-3, under SN 5565.

Survey and Biomeasures Data (GN 33004):
To date there have been nine attempts to trace all members of the birth cohort in order to monitor their physical, educational and social development. The first three sweeps were carried out by the National Children's Bureau, in 1965, when respondents were aged 7, in 1969, aged 11, and in 1974, aged 16 (these sweeps form NCDS1-3, held together with NCDS0 under SN 5565). The fourth sweep, also carried out by the National Children's Bureau, was conducted in 1981, when respondents were aged 23 (held under SN 5566). In 1985 the NCDS moved to the Social Statistics Research Unit (SSRU) - now known as the Centre for Longitudinal Studies (CLS). The fifth sweep was carried out in 1991, when respondents were aged 33 (held under SN 5567). For the sixth sweep, conducted in 1999-2000, when respondents were aged 42 (NCDS6, held under SN 5578), fieldwork was combined with the 1999-2000 wave of the 1970 Birth Cohort Study (BCS70), which was also conducted by CLS (and held under GN 33229). The seventh sweep was conducted in 2004-2005 when the respondents were aged 46 (held under SN 5579), the eighth sweep was conducted in 2008-2009 when respondents were aged 50 (held under SN 6137) and the ninth sweep was conducted in 2013 when respondents were aged 55 (held under SN 7669).

Four separate datasets covering responses to NCDS over all sweeps are available. National Child Development Deaths Dataset: Special Licence Access (SN 7717) covers deaths; National Child Development Study Response and Outcomes Dataset (SN 5560) covers all other responses and outcomes; National Child Development Study: Partnership Histories (SN 6940) includes data on live-in relationships; and National Child Development Study: Activity Histories (SN 6942) covers work and non-work activities. Users are advised to order these studies alongside the other waves of NCDS.

From 2002-2004, a Biomedical Survey was completed and is available under End User Licence (EUL) (SN 8731) and Special Licence (SL) (SN 5594). Proteomics analyses of blood samples are available under SL SN 9254.

Linked Geographical Data (GN 33497):
A number of geographical variables are available, under more restrictive access conditions, which can be linked to the NCDS EUL and SL access studies.

Linked Administrative Data (GN 33396):
A number of linked administrative datasets are available, under more restrictive access conditions, which can be linked to the NCDS EUL and SL access studies. These include a Deaths dataset (SN 7717) available under SL and the Linked Health Administrative Datasets (SN 8697) available under Secure Access.

Additional Sub-Studies (GN 33562):
In addition to the main NCDS sweeps, further studies have also been conducted on a range of subjects such as parent migration, unemployment, behavioural studies and respondent essays. The full list of NCDS studies available from the UK Data Service can be found on the NCDS series access data webpage.

NCDS8:
The eighth sweep of NCDS was conducted in 2008-2009, when respondents were aged 50 years. The core aims of the NCDS8 were to update the life history information collected in previous studies and to collect new information to help understand the ageing process. Many of the questions in the NCDS8 follow-up had been asked in earlier waves of the NCDS and the BCS, which will allow for the making of comparisons both across the sweeps of NCDS and with the BCS cohort.

The 2008-2009 survey is comprised of the following elements:

• a 55 minute a 'core' interview (included a Computer Assisted Personal Interview (CAPI); Computer Assisted Self Interview (CASI); a series of cognitive assessments)
• a paper questionnaire

Edition history:
The NCDS8 has been deposited at the UK Data Archive in stages. For the first Archive edition (March 2009) an interim data file was deposited, based on 2,997 interviews completed between August and December 2008. This file comprised a subset of the full list of variables.
The second Archive edition (the first full sample edition) was released in February 2010. This deposit included responses to the bulk of the questions fielded to cohort members in 2008-2009. The variables that were not included in this file were essentially those that required the most complex post-fieldwork editing in order to make them usable, mostly those that related to the four 'history' modules; housing history, relationship history, fertility history and economic activity history. In addition, variables relating to absent children, older children and specific details of recently-achieved qualifications were not included (although a series of derived summary variables relating to highest qualification were).
For the third Archive edition (October 2012), the final version of NCDS8 was deposited. Two files, 'ncds_2008_followup.sav' and 'ncds8_unfolding_brackets.sav' replaced the previous single data file, a new User Guide replaced the previous version, and the Technical Report and Appendices were added to the documentation. For further details, see the User Guide.

SN 8547 - 1970 British Cohort Study: Age 46, Sweep 10, 2016-2018:
The aim of the 46-year follow-up was to collect key details of the cohort members’ lives including their socio-economic circumstances (e.g. household composition, cohabiting relationships, housing, economic activity, and income) and their health (physical health, mental health, medication, and health behaviours). This survey had a significant biomedical focus, with objective health measurements and assessments being conducted for the first time in the cohort members’ adulthood.

The 'bcs_age46_child_died' and 'bcs_age46_unsuccessful_pregnancies' datasets
This note is to inform researchers that the 'bcs_age46_child_died' and 'bcs_age46_unsuccessful_pregnancies' datasets, which were previously available as safeguarded data under EUL, have been classified as controlled data by CLS and can only be accessed via the UKDS SecureLab, subject to the UKDS Secure Access licence. The aim of this note is to provide practical information and guidance to researchers who have downloaded the BCS70 Age 46 datasets 'bcs_age46_child_died' and 'bcs_age46_unsuccessful_pregnancies' from the UK Data Archive. CLS requires that all EUL holders delete their versions of these datasets. Should they require them, users can apply for access through the new Secure Access study SN 9115. However, where a user has downloaded these dataset and is using them in a current project, they may continue to use the data and any outputs derived from their use until the project is completed. On completion of the project, users are then required to delete the original datasets. Future projects should use the new versions of the data. Any users having concerns about this should contact CLS. Further guidelines on destroying data are provided in the UKDS guidelines.

Latest edition information
For the second edition (July 2023), a new data file including newly derived nutritional intake variables based on the food composition table from the UK Nutrient Databank (UKNDB) has been added to the study.

National Child Development Study: Understanding Individual Behaviour, 2010 is a pilot study completed by an inter-disciplinary network of researchers as part of the ESRC’s Understanding Individual Behaviour programme. The network’s core aim was to explore individual differences in mid-life cognitive capacity and how these relate to experiences and behaviour earlier in life.

The pilot study was conducted with a sub-sample of NCDS members living in and around Cambridge in 2010, when study members were aged 52, and sought to investigate the potential for conducting neuro-psychological assessments with purposive sub-samples from the British Birth Cohort Studies. The aim was to recruit individuals with particular cognitive ability trajectories between childhood and mid-adulthood. Childhood cognitive ability was measured using the age 11 General Ability Test (GAT). Adult cognitive ability was measured using cognitive assessments conducted at age 50. Potential participants were invited to a research centre at the University of Cambridge to complete a 90 minute testing session which involved three main elements:

• 1. Repetition of the cognitive assessments included in the NCDS age 50 survey (NCDS8): a) Word-list recall/delayed word-list recall - a test of verbal learning and recall; b) Animal naming - a test of verbal fluency; c) Letter cancellation - a test of attention, mental speed and visual scanning.
• 2. Five CANTAB (Cambridge Neuropsychological Test Automated Battery) tasks: a) Paired Associates Learning test (PAL) - a visuospatial associative learning test which assesses visual memory and new learning; b) Graded Naming Test (GNT) - a test of semantic and/or verbal memory; c) Affective Go/No-go(AGN) - a test of affective decision making and information processing biases; d) Cambridge Gambling Task (CGT) - a test of decision making and risk taking; and e) Rapid Visual Information Processing (RVP) - a test of attention and general information processing.
• 3. A short self-completion questionnaire.

In total, 45 study members participated in the pilot study.

Further information is available from investigating the genetic, social and neuropsychological influences on individual differences in impulsivity and in memory using a lifecourse approach ESRC Award web page.
