Did you know that your answers to just a handful of questions can predict the zip code of where you grew up? In 2013, Josh Katz accumulated and visually mapped over 350,000 unique survey responses to questions about word choice and pronunciation throughout America. His dialect quiz quickly became the most viewed webpage in the history of The New York Times. In SPEAKING AMERICAN, Katz offers a visual atlas of the American vernacular --- who says what, and where they say it --- revealing the history of our nation, our regions and our language.
