The award-winning journalist reveals the untold story of why America is so culturally and politically divided in this groundbreaking book. Armed with startling demographic data, Bill Bishop demonstrates how Americans have spent decades sorting themselves into alarmingly homogeneous communities—not by region or by state, but by city and neighborhood. With ever-increasing specificity, we choose the communities and media that are compatible with our lifestyles and beliefs. The result is a country that has become so ideologically inbred that people don't know and can't understand those who live just a few miles away. In The Big Sort, Bishop explores how this phenomenon came to be, and its dire implications for our country. He begins with stories about how we live today and then draws on history, economics, and our changing political landscape to create one of the most compelling big-picture accounts of America in recent memory.
