Possibly secularists tend to avoid living in the city center, but also avoid living in rural areas. This puts them in the suburbs. Of course, it may just be that the total population of suburbs is greater than that of the urban and rural areas.
I, too, live in the suburbs—outside of Los Angeles.
Ah. NYC… I miss it. It’s hard to find good bread and begals in the Midwest. Heh heh, there is actually a restaurant out here that is flying in fish, daily, if you can believe that! That’s because the Great Lakes, much less the ocean, is far away.
