What to Expect When No One's Expecting

What to Expect When No One's Expecting: America's Coming Demographic Disaster is a book by the Weekly Standard columnist Jonathan V. Last about declining birth rates in the United States and elsewhere around the world and the implications for demographics and the functioning of society and the economy (hardcover release February 2013, paperback release June 2014).

Reception
Nick Gillespie, editor of Reason magazine, reviewed the book on Bookforum, saying that he was convinced by Last's argument that birthrates were declining and there was not much that could be done about it, but found Last's account of the negative consequences exaggerated.

David Desrosiers reviewed the book favorably for Washington Times, writing that Last has argued that declining birthrates are largely a consequence of the changes set in motion by the Enlightenment rather than of any specific government policies, though policies by US liberals may have sped up the decline. Stanley Kurtz and Bradford Wilcox wrote separate reviews of the book for National Review.

William McGurn, editor of the New York Post, reviewed the book favorably for the Wall Street Journal, but was critical of Last for having 'too much confidence' in his pessimistic scenarios. McGurn concluded: "In theory, it's all certainly possible. But as Mr. Last reminds us, we do well to be modest about our predictions. Because the one thing the math tells us is this: We've never been here before."

Walter Russell Mead reviewed the book for Foreign Affairs.
