A groundbreaking, “lavishly informative” ( The New York Times ) portrait of the six generations that currently live in the United States and how they connect, conflict, and compete with one another—from the acclaimed author of Generation Me and iGen. Upending the conventional theory that generational differences are caused by major events, Dr. Jean Twenge analyzes data on 39 million people from robust national surveys—some going back nearly a century—to show that changes in technology are the underlying driver of each generation’s unique makeup. In this revelatory work, Twenge outlines key shifts in attitudes and lifestyle choices that define each generation regarding gender, income, politics, race, sexuality, marriage, mental health, and much more. Surprising, engaging, and informative, Generations “gets you thinking about how appreciating generational differences can, ironically, bring us together” (Angela Duckworth, New York Times bestselling author). It will forever change the way you view your parents, peers, coworkers, and children, no matter which generation you call your own.
