A Nation of Emigrants: How Mexico Manages Its Migration
"I spoke to economists and experts and Mexico and the United States but I settled on Arandas and Agua Negra because there was a robust historical record of emigration there, with Paul S. Taylor's book from the 30s and a more recent book - "A Nation of Emigrants" by David Fitzgerald, a professor at the University of California, San Diego. This was a baseline for me that, I figured, would let me really compare the present moment with the past." -New York Times
