The Origins of Happiness
Some Key Findings
- Income. Within most advanced countries income
differences explain only 1% of the variation in hap-
piness across people (other things equal),^2 while
all the factors we can identify explain 15% of the
variation. Doubling a person’s income raises their
happiness by under 0.2 points (on a scale of 0– 10).
Moreover people care largely about their income
relative to other people. So general increases in in-
come have very small impacts on overall happiness
in a society.
- Unemployment. By contrast unemployment is in it-
self an unalloyed bad. It reduces the happiness of
each unemployed person by about 0.7 points on
average. And it also creates fear and unease among
people who are in work: the unemployment of one
person reduces the aggregate happiness of the rest
of the community by another 2.0 points. So eco-
nomic policy should give strong priority to the aim
of economic stability,^3 and less importance to the
aim of long- term economic growth.
- Family life. Being partnered rather than single raises
happiness by 0.6 points, and losing a partner by
separation or death reduces happiness by a roughly
equal amount. As with being employed, people
need to be needed, and to be in meaningful rela-
tionships.
- Mental health. The biggest single predictor of indi-
vidual happiness is mental health. Suffering from
depression or anxiety disorders is more common
