Self-reported subjective wellbeing can be further divided into life satisfaction surveys (ranks of 0 to 10 of a person’s satisfaction with life) and emotional wellbeing indicators (a person’s emotional feelings at a point in time) (Kahneman and Deaton, 2010, Di Telia etal, 2001). Studies based on self-reported life satisfaction avoid these problems, but are subject to challenging data interpretation issues. These studies, which are getting increasing attention in the literature (Helliwell et al, 2008 and 2009), tend to show that self-reported subjective wellbeing has a strong correlation with income, but also that other factors, such as health, unemployment and divorce, or quality of life indicators based on objective outcomes, are important.
