Why this indicator was originally chosen

As an overall indicator of health, the best available option is one of the general health questions which ask survey respondents to assess their own health.  Self-reported health has been shown to be a reliable predictor of mortality style independent of other measures. Health Survey for England, Department of Health, 1996, page 184.  This report also points out that the most commonly reported specific conditions among adults were related to the musculoskeletal system, followed by the heart and circulatory system, and the respiratory system.

The biggest group of people who are economically inactive but want paid work are the long-term sick and disabled From the 2003 Spring Quarter of the Labour Force Survey: around 700,000 people are economically inactive, long-term sick or disabled, and want paid work.  This is two-fifths of the total number of economically inactive people who want paid work. and the prevalence of such illness or disability is much greater among those on lower incomes than among those on higher incomes.

The chosen indicator concerns whether people consider that their range of activities is limited because of their health problems or any disabilities they have.

Definitions and data sources

The first graph shows the proportion of adults aged 45 to 64 who report having a long-term illness or a disability that limits the activities they are able to carry out.  The data is shown separately for men and women.

The second graph show the same information but in terms of absolute numbers rather than proportions of the population.  ONS revised population estimates - which take account of the 2001 Census - have been used to derive the numbers from the proportions.

The third graph shows how the proportions vary by household income.  Again, the data is shown separately for men and women.  To improve its statistical reliability, the data is the average for the latest three years.  Note that the household incomes have been 'equivalised' (adjusted) for household size and composition.

The fourth graph shows how the proportions vary between social classes for men and women combined.  To improve its statistical reliability, the data is the average for the latest three years.

The National Statistics Socio-economic Classification (NS-SEC) has been used for all official statistics and surveys since 2001.  It replaced Social Class based on Occupation (SC, formerly Registrar General's Social Class) and Socio-economic Groups (SEG).  ONS felt that a system of categorisation based on skill levels was outmoded and misleading given changes in the nature and structure of industry and occupations. 

A person's NS-SEC position (their 'class') depends upon the combination of their current or last main job and their employment status (i.e. whether an employer, self-employed, a manager, a supervisor or an employee).  A person's job title is coded according to one of the 353 unit groups (consisting of 26,000 job titles) of the Standard Occupational Classification (SOC), and their employment status is coded according their employment relations and the size of their organisation.  These codes are transferred into eight analytical classes, which have then been collapsed into three ('simplified') analytical classes for the purposes of the graph.

The data source for the first four graphs is the General Lifestyle Survey (formerly called the General Household Survey) and relates to Great Britain.  The question asked was "Do you have any long-standing illness, disability or infirmity? Long-standing is anything that has troubled you over a period of time or that is likely to affect you over a period of time.  Does this illness or disability limit your activities in any way?"  Note that:

The fifth graph shows how the proportion of people aged 45 to 64 self-reporting a limiting long-standing illness varies by region.

The map shows how the proportion of people aged 16 to 59 self-reporting a limiting long-standing illness varies by small area.

The data source for the fifth graph and map is the 2001 Census (table so017 for England and Wales, S16 for Scotland and S016 for Northern Ireland).

Overall adequacy of the indicator: medium.  While the General Lifestyle Survey is a well-established government survey designed to be representative of the population as a whole, the inevitable variation in what respondents understand and interpret as 'long-standing' and 'limiting activity' diminishes the value of the indicator.
