Updated to include a new chapter about the influence of social media and the Internet–the 20th anniversary edition of Bowling Alone remains a seminal work of social analysis, and its examination of what happened to our sense of community remains more relevant than ever in today’s fractured America.

Twenty years, ago, Robert D. Putnam made a seemingly simple observation: once we bowled in leagues, usually after work; but no longer. This seemingly small phenomenon symbolized a significant social change that became the basis of the acclaimed bestseller, Bowling Alone, which The Washington Post called “a very important book” and Putnam, “the de Tocqueville of our generation.”

Bowling Alone surveyed in detail Americans’ changing behavior over the decades, showing how we had become increasingly disconnected from family, friends, neighbors, and social structures, whether it’s with the PTA, church, clubs, political parties, or bowling leagues. In the revised edition of his classic work, Putnam shows how our shrinking access to the “social capital” that is the reward of communal activity and community sharing still poses a serious threat to our civic and personal health, and how these consequences have a new resonance for our divided country today. He includes critical new material on the pervasive influence of social media and the internet, which has introduced previously unthinkable opportunities for social connection–as well as unprecedented levels of alienation and isolation.

At the time of its publication, Putnam’s then-groundbreaking work showed how social bonds are the most powerful predictor of life satisfaction, and how the loss of social capital is felt in critical ways, acting as a strong predictor of crime rates and other measures of neighborhood quality of life, and affecting our health in other ways. While the ways in which we connect, or become disconnected, have changed over the decades, his central argument remains as powerful and urgent as ever: mending our frayed social capital is key to preserving the very fabric of our society.

A New York Times bestseller and “a passionate, urgent” (The New Yorker) examination of the growing inequality gap from the bestselling author of Bowling Alone: why fewer Americans today have the opportunity for upward mobility.

Central to the very idea of America is the principle that we are a nation of opportunity. But over the last quarter century we have seen a disturbing “opportunity gap” emerge. We Americans have always believed that those who have talent and try hard will succeed, but this central tenet of the American Dream seems no longer true or at the least, much less true than it was.

In Our Kids, Robert Putnam offers a personal and authoritative look at this new American crisis, beginning with the example of his high school class of 1959 in Port Clinton, Ohio. The vast majority of those students went on to lives better than those of their parents. But their children and grandchildren have faced diminishing prospects. Putnam tells the tale of lessening opportunity through poignant life stories of rich, middle class, and poor kids from cities and suburbs across the country, brilliantly blended with the latest social-science research.

“A truly masterful volume” (Financial Times), Our Kids provides a disturbing account of the American dream that is “thoughtful and persuasive” (The Economist). Our Kids offers a rare combination of individual testimony and rigorous evidence: “No one can finish this book and feel complacent about equal opportunity” (The New York Times Book Review).

From the author of Bowling Alone and Our Kids, a “sweeping yet remarkably accessible” (The Wall Street Journal) analysis that “offers superb, often counterintuitive insights” (The New York Times) to demonstrate how we have gone from an individualistic “I” society to a more communitarian “We” society and then back again, and how we can learn from that experience to become a stronger more unified nation.

Deep and accelerating inequality; unprecedented political polarization; vitriolic public discourse; a fraying social fabric; public and private narcissism–Americans today seem to agree on only one thing: This is the worst of times.

But we’ve been here before. During the Gilded Age of the late 1800s, America was highly individualistic, starkly unequal, fiercely polarized, and deeply fragmented, just as it is today. However as the twentieth century opened, America became–slowly, unevenly, but steadily–more egalitarian, more cooperative, more generous; a society on the upswing, more focused on our responsibilities to one another and less focused on our narrower self-interest. Sometime during the 1960s, however, these trends reversed, leaving us in today’s disarray.

In a “magnificent and visionary book” (The New Republic) drawing on his inimitable combination of statistical analysis and storytelling, Robert Putnam analyzes a remarkable confluence of trends that brought us from an “I” society to a “We” society and then back again. He draws on inspiring lessons for our time from an earlier era, when a dedicated group of reformers righted the ship, putting us on a path to becoming a society once again based on community. This is Putnam’s most “remarkable” (Science) work yet, a fitting capstone to a brilliant career.
