Religion in America


America's Most (and Least) Religious Metro Areas

Religion in America has an unmistakable geographic dimension


Three of the top five most religious metros are in Alabama — Montgomery, Birmingham, and Huntsville. Jackson, Mississippi, also ranks among the top five.

Burlington, Vermont, and Boulder, Colorado, tie for the title of the nation's least religious metro area. In these two metros, fewer than one in five residents claim to be "very religious." San Francisco and Boston also rank among the least religious metros in America.

These patterns conform to the broader findings of political scientist Ronald Inglehart, whose detailed World Values Surveys identify the shift from religious to secular values as one part of the transition to more economically advanced societies. Politicos on the left and right like to explain religious voters' proclivity purely in terms of values. But this misses a central point - that religion is inextricably bound up with the nation's underlying economic and geographic class divide.

A 'Whom Do You Hang With?' Map Of America

A website that tracks the movement of dollar bills. 
Lines that the money rarely crossed are noted in blue. ^

Money-in-motion is one proxy for how people connect. 
Yakking on the phone is another. 

Pretty Interesting (especially the dollar tracking data build)

The Shape of Song in Images

Chopin, Mazurka in F# Minor

The image illustrates the complex, nested structure of the piece.
Diagrams in The Shape of Song display musical form as a sequence of translucent arches. Each arch connects two repeated, identical passages of a composition. By using repeated passages as signposts, the diagram illustrates the deep structure of the composition.

This is cool!
