Two centuries ago there was relatively little dispute over the existence of God, or the societally beneficial effect of popular belief in a creator. In the twentieth century extensive secularization occurred in western nations, the United States being the only significant exception (Bishop; Bruce; Gill et al.; Sommerville). If religion has receded in some western nations, what is the impact of this unprecedented transformation upon their populations? Theists often assert that popular belief in a creator is instrumental towards providing the moral, ethical and other foundations necessary for a healthy, cohesive society. Many also contend that widespread acceptance of evolution, and/or denial of a creator, is contrary to these goals. But a cross-national study verifying these claims has yet to be published. That radically differing worldviews can have measurable impact upon societal conditions is plausible according to a number of mainstream researchers (Bainbridge; Barro; Barro and McCleary; Beeghley; Groeneman and Tobin; Huntington; Inglehart and Baker; Putman; Stark and Bainbridge). Agreement with the hypothesis that belief in a creator is beneficial to societies is largely based on assumption, anecdotal accounts, and on studies of limited scope and quality restricted to one population (Benson et al.; Hummer et al.; Idler and Kasl; Stark and Bainbridge). A partial exception is given by Barro and McCleary, who correlated economic growth with rates of belief in the afterlife and church attendance in numerous nations (while Kasman and Reid  commented that Europe does not appear to be suffering unduly from its secularization). It is surprising that a more systematic examination of the question has not been previously executed since the factors required to do so are in place. The twentieth century acted, for the first time in human history, as a vast Darwinian global societal experiment in which a wide variety of dramatically differing social-religious-political-economic systems competed with one another, with varying degrees of success. A quantitative cross-national analysis is feasible because a large body of survey and census data on rates of religiosity, secularization, and societal indicators has become available in the prosperous developed democracies including the United States.
 This study is a first, brief look at an important subject that has been almost entirely neglected by social scientists. The primary intent is to present basic correlations of the elemental data. Some conclusions that can be gleaned from the plots are outlined. This is not an attempt to present a definitive study that establishes cause versus effect between religiosity, secularism and societal health. It is hoped that these original correlations and results will spark future research and debate on the issue.
