Surveys vary in their methodology, sample size, and in the age ranges they cover, and their results may not be directly comparable.
The Scottish Household Survey (08/09 results published August 2010) aims to give early detection of national trends.:
The Scottish Health Survey (to date conducted in 1995, 1998, 2003 and 2008 results published in 1997, 2000, 2005 and 2009 respectively) offers the most robust statistical analysis of adult smoking rates in Scotland based on sample size. It is restricted to the age range 16-74.
The ONS General Household Survey data gives a longer timescale for identifying trends, and allows for a comparison with overall smoking prevalence in Great Britain.
