National Survey of Sexual Attitudes and Lifestyles
The National Survey of Sexual Attitudes and Lifestyles is the name given to a series of face-to-face surveys of people in the United Kingdom regarding their sexual behaviour and patterns. The three rounds of interviews completed to date are NATSAL-1 and NATSAL-2 and NATSAL-3. The results are widely used in research and policy making. NATSAL's principal investigator is Anne Johnson, a professor at University College, London, and co-leader Kaye Wellings, a professor at the London School of Hygiene & Tropical Medicine.
The Natsal-3 survey revealed, among other things, that British people are having sex less often than they did 20 years ago.*
