As with many chapters in edited volumes, this one doesn't have an abstract. The bulk of the chapter is an analysis of the asexuality data in NATSAL-II, primarily examining the same things that Bogaert's 2004 paper on asexuality examined with the NATSAL-I data.
For those unfamiliar with it, the National Survey of Sexual Attitudes and Lifestyles
is the largest scientific study of sexual behaviour since the pioneering studies of Alfred Kinsey in the US in the 1940s and 1950s.
Natsal was originally set up because of an urgent need for information about sexual lifestyles in the context of the HIV/ AIDS epidemic.
Natsal first took place in 1990, with the second study taking place in 2000. The third Natsal began in 2010 and its results will be published in 2013.
