And of course, I couldn't not do an annotated version.
When you say "Heavily Christian", do you mean Evangelicals or conservative mainline Protestants or just churchy people in general?
There's a sizeable Evangelical population (one of the largest megachurches in the USA is in South Barrington). It reminds me a bit of the rich populations of Orange County, whereas the North Shore is more like the rich populations of suburban New York or Boston.
I really want to do the same map but for the 2012 Presidential because that map would really show how different wealthy people in the Barrington area are from wealthy people along the North Shore.
yep, Barrington was part of Phil Crane's district years ago, who was sort of a Ted Cruz type.
