The Opinions and Lifestyle Survey is a regular, multi-purpose survey which started operating commercially in 1990. It was carried out in eight months of the year until April 2005, when it began to run monthly. It was originally set up to meet the needs of government departments for a survey that used short and simple sets of questions, had greater statistical reliability than private sector omnibus surveys and a properly designed random sample. Each month's questionnaire consists of two elements: core demographic questions, and non-core questions that vary from month to month. From April 2012 the ONS Opinions Survey changed its name to the Opinions and Lifestyle Survey following the merger of some elements from the General Lifestyle Survey (GLF).
Repeated cross-sectional study: monthly
1990 to 2007, 2008 to present.
