The New York Times bestselling investigation into the sexual, economic, and emotional lives of women is "an informative and thought-provoking book for anyone--not just the single ladies ( The New York Times Book Review ).     In 2009, award-winning journalist Rebecca Traister started All the Single Ladies about the twenty-first century phenomenon of the American single woman. It was the year the proportion of American women who were married dropped below fifty per¢ and the median age of first marriages, which had remained between twenty and twenty-two years old for nearly a century (1890-1980), had risen dramatically to twenty-seven.     But over the course of her vast research and more than a hundred interviews with academics and social scientists and prominent single women, Traister discovered a startling truth: the phenomenon of the single woman in America is not a new one. And historically, when women were given options beyond early heterosexual marriage, the results were massive social change--temperance, abolition, secondary education, and more. Today, only twenty percent of Americans are married by age twenty-nine, compared to nearly sixty percent in 1960.     All the Single Ladies is a remarkable portrait of contemporary American life, through the lens of the unmarried American woman. Covering class, race, sexual orientation, and filled with vivid anecdotes from fascinating contemporary and historical figures, "we're better off reading Rebecca Traister on women, politics, and America than pretty much anyone else" ( The Boston Globe ).
