I don't mean to overstate the reliability of suicide rates for happiness. A variety of factors may influence them. However, there are reasons to believe they correlate with happiness.
What is a good measure of happiness? Virtually all measures are deeply flawed, but the most reliable is probably: Intra-observer self-report in situations when signalling is unlikely. People are probably decent at knowing when they were happier or less happy within their own lives. Inter-observer reports are far harder to justify.
People report being happier when they live in places with adequate sunshine; inadequate sunshine correlates with increased suicide rates. People report being happier when they are not facing loss of job, public humiliation, divorce, and a number of other events; these events correlate with increase suicide rates. People report being happier when mental illness symptoms are reduced (particularly depression); people with mental illness (particularly depression) have a higher suicide rate.
Obviously, suicide rates are not a perfect proxy for happiness... but I cannot find a more reliable easily-measured statistic.
I was browsing my RSS feed, as one does, and came across a New York Times article, "A Village With the Numbers, Not the Image, of the Poorest Place", about the Satmar Hasidic Jews of Kiryas Joel (NY).
Their interest lies in their extraordinarily high birthrate & population growth, and their poverty - which are connected. From the article:
From Wikipedia:
Robin Hanson has argued that uploaded/emulated minds will establish a new Malthusian/Darwinian equilibrium in "IF UPLOADS COME FIRST: The crack of a future dawn" - an equilibrium in comparison to which our own economy will look like a delusive dreamtime of impossibly unfit and libertine behavior. The demographic transition will not last forever. But despite our own distaste for countless lives living at near-subsistence rather than our own extreme per-capita wealth (see the Repugnant Conclusion), those many lives will be happy ones (even amidst disaster).
So. Are the inhabitants of Kiryas Joel unhappy?
