In 2013, Josh Katz created a dialect quiz for the New York Times that received more than 350,000 responses and became the most-viewed page in the newspaper's history. From the survey results came this series of colorful maps depicting the varying terms used for certain items across the United States. Where is a sale of household items called a "tag sale," as opposed to a "yard sale," "garage sale," or "rummage sale"? Where do people wear "tennis shoes" instead of "sneakers"? Katz's maps and accompanying explanations will answer these and many more questions about how America speaks.
