The OECD unveiled a new index on the 24th May that measures well-being in a way that attempts to go beyond GDP. The Better Life Index is based on 11 dimensions -- housing, income, jobs, community, education, environment, governance, health, life satisfaction, safety and work-life balance. There are two health indicators; average number of years a person can expect to live and % of people reporting their health to be "good or very good". The life satisfaction indicator relates to a single self-evaluation of life satisfaction, on a scale from 0 to 10.
In common with other composite indices for international comparisons, each indicator is normalised then weighted to produce an overall score and ranking. One key difference with the Better Life Index is that the weighting can be adjusted by the user to better reflect what they feel is important. So, for example, you can see what impact health indicators have on the overall measure.
Whatever you do, the UK is never top of the list. So it appears to have face validity, at least.
