The Avon Longitudinal Study of Parents and Children (ALSPAC), also known as Children of the 90s, is a world-leading birth cohort study based in the University of Bristol. Over 14,000 children, born from pregnancies with due dates between April 1991 and December 1992, and their families, have been intensively observed for over 25 years. The data collected by the study provides a rich resource for the study of the environmental and genetic factors that affect health and development.

While the research data amassed by ALSPAC has long been available to scientists, the extensive administrative archive (over 1,000 boxes of records) documenting the study from the earliest planning stages to 2005 has not been generally accessible. Following a grant from the Wellcome Trust and the University of Bristol Alumni Foundation, work on cataloguing the archive commenced in September 2015. A catalogue of collection and series level descriptions was launched in April 2018. 

Use of the archive is subject to approval from ALSPAC and access restrictions apply to records containing sensitive and personal data. All participant information has been withdrawn from the archive in line with ALSPAC’s strict confidentiality policy. Most post-2005 records will not be available.
