Generations: The Real Differences Between Gen Z, Millennials, Gen X, Boomers, and Silents—and What They Mean for America's Future

A groundbreaking, revelatory portrait of the five generations that make up today’s population, from the bestselling author of Generation Me and iGen. Dr. Jean Twenge has analyzed millions of data points to glean the attitudes, characteristics, and life circumstances that define each generation, resulting in a fascinating look at how they connect, conflict, and compete with each other.

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.
