Erica Goode had an abbreviated account of our research on immigration, diversity and social cohesion called “Home Alone” (New York Times Sunday Magazine, 6/17/07). [Much of here article is reprinted in an Creative Class Group blog post if you are not a Times Select subscriber, although if you read this blog, read the first comment that our work already does control for mobility, at the individual and community level, so the effects we find are for diversity, net of any changes in individual or aggregate mobility.]
There’s a deeper, more thorough account of our research by Madeleine Bunting in “Immigration Is Bad For Society, But Only Until A New Solidarity Is Forged” (Guardian, 6/18/07).
And of course the fullest account of our research can be found in the original article which is quite accessible and interesting. It is called E Pluribus Unum: Diversity and Community in the 21st Century. The 2006 Johan Skytte Lecture by Robert D. Putnam and appears in the June 2007 Scandinavian Political Studies Journal.
