From the series Oaxacan Exodous
Nearly 500,000 indigenous Mexican immigrants, mostly Mixtecos, Zapotecos and Triquis, from the state of Oaxaca, are now estimated to be living in the United States. They are among the most isolated immigrants ever to arrive in America. Some speak only their indigenous language, and some come from villages without cars, electricity, or indoor plumbing.
In California’s Central Valley, where over half of these new migrants have settled, they are quickly becoming a new rural underclass. Living on the fringes of the Valley’s farm labor economy, and isolated by their culture and language, they suffer some of the worst abuses and exploitation in the country.
