Religious people are statistically happier on average than non-religious people.
Just thought I should go back to this, because a lecture I happened to listen to recently speaks to this point. If it's correct, then your claim isn't actually true... or at least, there's more to it.
(BTW - the lecture is "The Roots of Morality: Does Religion Play a Role or Is the Tail Wagging the Dog?" by Luke Galen. It's available for download as the April 14 episode of the Reasonable Doubts podcast. I don't have a direct link, but you can find it through iTunes)
One of the things that Dr. Galen touched on in his lecture was the point I think you're alluding to: there
have been studies that show a correlation between regularity of church attendance with scores on various indicators of happiness. However, Dr. Galen points out a problem with these sorts of studies: the "church non-attender" group includes two distinct sub-groups:
- people who just don't care about religion enough to go to church: the apathetic.
- people who care (sometimes deeply) about religion, but don't attend church
because of those beliefs: for instance atheists and other explicit "non-believers".
Dr. Galen did his own study to account for this co-mingling of these groups by looking at the happiness of non-believers relative to how often they attend meetings of non-religious groups (he gave CFI as an example). What he found was that people who attended non-religious meetings frequently were just as happy as the people who attended church services frequently.
He hypothesized two potential factors to explain this effect:
- churches and religious groups both give similar social benefit through interaction and the sense of belonging to a community.
- the actual predictor of happiness is certainty of belief about religious subjects,
whether for or against, not religious faith specifically.
So... it appears that the very irreligious are just as happy as the very religious, and the mildly religious are comparably less happy than both of them.
Now... I'd like to go back to something else we discussed on before: the effects of religion on other people's happiness. Dr. Galen touched on something else: the different approaches that different groups have toward morality. He mentioned (as I've heard from other sources) that in general, religious and political conservatives tend to base their morality on five different factors:
- Harm/Care, which is the universal desire to minimize human suffering.
- Fairness/Reciprocity, which is more or less about a desire to see arguments and disputes handled fairly.
- Ingroup/Loyalty, which describes the desire to protect group membership (societal) boundaries.
- Authority/Respect, which concerns the desire to organize society into a hierarchy of social superiors and subordinates, with subordinates showing respect for the superior's superior position.
- Purity/Sanctity, which concerns the desire to maintain group membership in a pristine, pure, clean or proper state, and correspondingly, to reject from the group that which is dirty, impure, unclean and improper.

OTOH, religious and political liberals tend to only base their morality on the first two factors. Dr. Galen called this "the morality of autonomy":
"if it's not unfair and it doesn't hurt anyone else, I won't stop you from doing it."
So... getting back to the subject at hand, since there seems to be a trend toward more conservative "group-based" morality among religious people and a trend toward more liberal "autonomy-based" morality among non-religious people, which do you think would be more likely to create an environment conducive to happiness for people who aren't part of the main group?
IOW, which would you rather be: the lone atheist in a community of religious people, or the lone religious person in a community of atheists?
Since religion's effect on happiness of the individual is basically a wash between religiosity and irreligiosity, I think the question of contribution to happiness comes down to religion's affect on the happiness of people "outside the group". I think that in general, irreligion does a better job with this than religion, so on the whole, I think that religion has a net negative effect on people's happiness.
