Daum spent much of her twenties in New York City. In 1999, she moved to Lincoln, Nebraska, and the experience became the catalyst for her 2003 novel The Quality of Life Report, which follows the life and times of an ambitious young television journalist who trades New York for the fictional town of Prairie City and explores themes of social class in America as well as the contradictions of the "simplicity movement." She is also the author of two collections of essays, My Misspent Youth and The Unspeakable: And Other Subjects of Discussion, which was named as a top 10 books of the year by Slate and Entertainment Weekly.[2] It won the 2015 PEN CENTER USA Literary Award for Creative Nonfiction.
Her work has appeared in The New Yorker, The New York Times Magazine, The Atlantic, Vogue, GQ, Harper's and elsewhere.
Daum lives in Los Angeles, California, and New York City. She has been an opinion columnist for the Los Angeles Times since 2005. She is a member of the adjunct faculty in the writing division of the School of the Arts at Columbia University.
