National Survey of Sexual Attitudes and Lifestyles

The National Survey of Sexual Attitudes and Lifestyles (NATSAL) 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 two rounds of interviews completed to date are NATSAL I (1990-91) and NATSAL II (2000-01). A third round of interviews is being conducted from 2010 to 2012. The results of the survey are widely used in research and policy making.
