Income

A person’s income is expressed in terms of the standardised disposable income.  For life expectancy by income, income data over 2006 from the Social Statistical Database (SSB) were linked to mortality data over 2007. For healthy life expectancy by income, data from the Integrated System of Social Surveys (POLS) from 2004, 2005, 2006 and 2007 were used. Incomes were linked to all POLS respondents in these years. As data on incomes over 2007 were not available at the time the survey was conducted, POLS respondents over 2007 were linked to their incomes over 2006.
