What to Expect When No One's Expecting: America's Coming Demographic Disaster is a book by the Weekly Standard columnist Jonathan V. Last arguing that there had been fewer people born than previously recorded around the world and why this could change society in the future.

[1] 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.

[2][3] 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.

[5] 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.

"[6] Additional reviews of What to Expect include Walter Russell Mead's for Foreign Affairs.
