Natsal-4 was in field from September 2022 to April 2024 and achieved a total sample of ~19,000 people aged 16-59 using a combination of sampling and data collection methods.
The project is being delivered by a multi-disciplinary team of researchers from University College London (UCL), the London School of Hygiene & Tropical Medicine (LSHTM), the University of Glasgow and NatCen Social Research (NatCen).
The Natsal Resource (including Natsal-4) is supported by a grant from the Wellcome Trust with contributions from the Economic and Social Research Council and the National Institute of Health Research.
