Norway, Iceland, Australia, Canada, Sweden, Switzerland, Belgium, Japan, the Netherlands, Denmark, and the United Kingdom are among the least religious societies on [E]arth. 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' [H]uman [D]evelopment [I]ndex are unwaveringly religious. Other analyses paint the same picture: the United States is unique among wealthy democracies in its level of religious adherence; it is also uniquely beleaguered 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.
