Sex by Numbers

What statistics can tell us about sexual behaviour

Book cover of Sex by Numbers by David Spiegelhalter

Yes. Yes. Yessssss. Finally: a book on statistics that the public will buy and want to read... Full of gems.

Danny Dorling, Times Higher education

Luckily, David Spiegelhalter is here to unravel the web of exaggerations, misdirections and downright lies that surround sex in modern society. Inspired by the Institute of Sexology exhibition and drawing on the Natsal survey (the widest survey of sexual behaviour since the Kinsey Report), he answers crucial questions such as What are we all doing? How often? And how has sex changed?

'Sex by Numbers' is an informed, entertaining and eye-opening look at the most enduring of human obsessions: from one-night stands to the seven-year itch.
