When we hear about the Nones — those who answer None of the Above when asked about their religious affiliation — it's usually about atheists and other secular types who skew higher in income and education. But many Nones have lower incomes, less than a college education and, often, less stable family lives. Many still believe in God and heaven, but don't belong to a faith group. Who are the Nones we don't know, and how do they fit into a wider picture of social and economic dislocation?
