Cross-sectional studies

Census microdata (formerly known as Samples of Anonymised Records or SARs): anonymised individual level records sampled from a single census which contain a wide range of individual and household characteristics so enable multivariate analyses for a range or purposes.

General Lifestyle Survey (formerly known as the General Household Survey): started in 1971 but was discontinued in 2012. It was based on a sample of around 10,000 private households in Great Britain (around 18,000 adults). Started in 1971; from 2009 it became part of the new Integrated Household Survey and included a longitudinal element.

Health Survey for England (HSE): annual surveys with a common core of questions and specific modules with a different focus for each year. Questions asked and sample populations vary from year to year depending on the focus.

Various ONS household and individual surveys.
