Natsal-4 data was collected 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 initial results from Natsal-4 will be published at the end of November 2026.
The Natsal-4 dataset will be archived on UK Data Archive by the end of 2026.
Natsal-4 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, University of Cambridge, Örebro University Hospital, and NatCen Social Research (NatCen).
The project is funded by a grant from the Wellcome Trust with contributions from the Economic and Social Research Council (ESRC) and the National Institute for Health and Care Research (NIHR).
