People who have conditions which they think have been caused or made worse by their current or past work, as estimated from the Labor Force Survey (LFS). Total cases (prevalence) includes long-standing as well as new (incidence) cases. New cases consist of those who first became aware of their illness in the last 12 months. Estimates are based on the most serious work-related illness, as defined by the individual, if they have more than one. HSE has collected data on ill health through the LFS, periodically since 1990 and annually from fiscal year 2001-2002, with the exception of fiscal years 2002-2003 and 2012-2013 when no ill health data was collected.
With roots stretching back to 1833 the modern HSE is an independent regulator with over forty years’ experience helping Great Britain work well. The Labor Force Survey is a survey of households living at private addresses in the UK. Its purpose is to provide information on the UK labor market which can then be used to develop, manage, evaluate and report on labor market policies. The survey is managed by the Office for National Statistics in Great Britain and by the Central Survey Unit of the Department of Finance and Personnel in Northern Ireland on behalf of the Department of Enterprise, Trade and Investment (DETINI).
Since 1992, the LFS in Great Britain has run as a quarterly survey (fiscal year 1994-1995 for Northern Ireland). The quarterly surveys have until spring 2006 operated on a seasonal quarter basis. However, mostly due to an EU requirement under regulation, in May 2006 the LFS moved to calendar quarters. The 2006-2007 fiscal year data is the first set of HSE data based on the LFS to be affected by this change. The LFS is intended to be representative of the whole population of the UK, and the sample design currently consists of around 37,000 responding households in every quarter. The quarterly survey has a panel design whereby households stay in the sample for five consecutive quarters (or waves), with a fifth of the sample replaced each quarter. Thus there is an 80% overlap in the samples for each successive survey.
