I hope we have American-topias.

I was surprised by how forces in the community could mobilize against a community changing. There were many examples of this. In St. George, members of the Latino community proposed having a "Dixie Fiesta." The resistance to that surprised me.

In the pioneer West Whitopias, immigration tended to be the dominant social and racial issue. In Forsyth County, Georgia, immigration is still an issue, but because you have that complicated history of the Trail of Tears and slavery and Jim Crow, the Whitopia has a different flavor.

There is tremendous long-term harm when Americans accept ethnic and class balkanization as a de facto fixture of American life. I think that impoverishes our understanding of each other.

Louisville, Colorado, which was just voted by CNN and Money magazine as the best place to live, is a veritable Whitopia that is unaffected by the housing crisis and even the severe recession. You look at the best places to live, according to Money's 2009 list, and 9 of the 10 are Whitopias.

By 2042, whites will no longer be the American majority.

I had been hearing on-the-ground buzz that white folks were moving to places like Bend, Oregon, and Coeur d'Alene, Idaho, and St. George, Utah. That led me to discover through census data that these towns were already extremely white and they were becoming, in most cases, even whiter. Statistics could only tell me so much; in order to get to the spirit and essence of it, I had to immerse myself.
