Some demographics relative to religion

I like to read a thoughful book slowly. I've been reading Sam Harris's thin Letter to a Christian Nation for several days but am only halfway through it. I just came across this passage, with some demographics relative to religion:

While you [the committed Christian whom the "letter" addresses] believe that bringing an end to religion is an impossible goal, it is important to realize that much of the developed world has nearly accomplished it. Norway, Iceland, Australia, Canada, Sweden, Switzerland, Belgium, Japan, the Netherlands, Denmark, and the United Kingdom are among the least religious societies on earth. According to the United Nations' Human Development Report (2005) they are also the healthiest, as indicated by life expectancy, adult literacy, per capita income, educational attainment, gender equality, homicide rate, and infant mortality. Insofar as there is a crime problem in Western Europe, it is largely the product of immigration. Seventy percent of the inmates of France's jails, for instance, are Muslim. The Muslims of Western Europe are generally not atheists. Conversely, the fifty nations now ranked lowest in terms of the United Nations' human development index are unwaveringly religious.

Other analyses paint the same picture: the United States is unique among wealthy democracies in its levels of religious adherence; it is also uniquely beleagured by high rates of homicide, abortion, teen pregnancy, sexually transmitted disease, and infant mortality. The same comparison holds true within the United States itself: Southern and Midwestern states, characterized by the highest levels of religious literalism, are especially plagued by the above indicators of societal dysfunction, while the comparatively secular states of the Northeast conform to European norms.

While political party affiliation in the United States is not a perfect indicator of religiosity, it is no secret that the "red states" are primarily red because of the overwhelming political influence of conservative Christians. If there were a strong correlation between Christian conservatism and societal health, we might expect to see some sign of it in red-state America. We don't. Of the twenty-five cities with the lowest rates of violent crime, 62 percent are in "blue" states and 38 percent are in "red" states. Of the twenty-five most dangerous cities, 76 percent are in red states, 24 percent in blue states. In fact, three of the five most dangerous cities in the United States are in the pious state of Texas. The twelve states with the highest rates of burglary are red. Twenty-four of the twenty-nine states with the highest rates of theft are red. Of the twenty-two states with the highest rates of murder, seventeen are red...

Countries with high levels of atheism are also the most charitable in terms both of the percentage of their wealth they devote to social welfare programs and of the percentage they give in aid to the developing world. The dubious link between Christian literalism and Christian values is belied by other indices of social equality. Consider the ratio of salaries paid to top-tier CEOs and those paid to the same firms' average employees: in Britain it is 24:1; in France, 15:1; in Sweden, 13:1; in the United States, where 80 percent of the population expects to be called before God on Judgment Day, it is 475:1. Many a camel, it would seem, expects to pass easily through the eye of a needle.

Of course, correlational data of this sort do not resolve questions of causality—belief in God may lead to societal dysfunction; societal dysfunction may foster a belief in God; each factor may enable the other; or both may spring from some deeper source of mischief. Leaving aside the issue of cause and effect, however, these statistics prove that atheism is compatible with the basic aspirations of a civil society; they also prove, conclusively, that widespread belief in God does not ensure a society's health.
