The National Survey of Sexual Attitudes and Lifestyles II, 2000-2001 (NATSAL II) was very closely modelled on the National Survey of Sexual Attitudes and Lifestyles, 1990-1991 (NATSAL I, held at the UKDA under SN 3434), carried out by the same team of investigators. The results from the first survey were widely used by academics and policymakers. Towards the end of the 1990s, it became increasingly clear that the NATSAL I results were growing outdated and that repeat measures were needed not only to provide up-to-date information for estimating the likely extent of the HIV epidemic in Britain, but also to look at behaviour change over time and to include new questions to take account of current information needs in the field of sexual health.
