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 datasets will be archived under Secure Access in the UK Data Archive in early 2027. Details of how to access data in UKDS’s SecureLab can be found here: [SecureLab link].

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).
