Bowling Alone: The Collapse and Revival of American Community is a 2000 nonfiction book by Robert D. Putnam. It was developed from his 1995 essay entitled "Bowling Alone: America's Declining Social Capital". Putnam surveys the decline of social capital in the United States since 1950. He has described the reduction in all the forms of in-person social intercourse upon which Americans used to found, educate, and enrich the fabric of their social lives. He argues that this undermines the active civic engagement which a strong democracy requires from its citizens. Contents Putnam discussed ways in which Americans disengaged from community involvement, including decreased voter turnout, attendance at public meetings, service on committees, and work with political parties. Putnam also cited Americans' growing distrust in their government. Putnam accepted the possibility that this lack of trust could be attributed to "the long litany of political tragedies and scandals since the 1960s", but believed that this explanation was limited when viewing it alongside other "trends in civic engagement of a wider sort". Putnam noted the aggregate loss in membership and number of volunteers in many existing civic organizations such as religious groups (Knights of Columbus, B'nai Brith, etc.), labor unions, parent–teacher associations, Federation of Women's Clubs, League of Women Voters, military veterans' organizations, volunteers with Boy Scouts and the Red Cross, and fraternal organizations (Lions Clubs, Benevolent and Protective Order of Elks, United States Junior Chamber, Freemasonry, Rotary, Kiwanis, etc.). Putnam used bowling as an example to illustrate this; although the number of people who bowled had increased in the last 20 years, the number of people who bowled in leagues had decreased. If people bowled alone, they did not participate in the social interaction and civic discussions that might occur in a league environment. Putnam cites data from the General Social Survey that showed an aggregate decline in membership of traditional civic organizations, supporting his thesis that U.S. social capital had declined. He noted that some organizations had grown, such as the American Association of Retired Persons, the Sierra Club, and a plethora of mass-member activist groups. But he said that these groups did not tend to foster face-to-face interaction, and were the type where "the only act of membership consists in writing a check for dues or perhaps occasionally reading a newsletter." He also drew a distinction between two different types of social capital: a "bonding" type (which occurs within
