Two of the Scottish Government's National Performance Framework (NPF) National Indicators are relevant to smoking. There is a specific indicator on reducing the proportion of adults who are current smokers, as well as a more general indicator on reducing premature mortality (deaths from all causes in those aged under 75), for which smoking is a significant contributory factor. The Scottish Survey Core Questions is an innovative project drawing together multiple household surveys to provide a large sample for subnational analysis. For more information on this source, see the [SSCQ website](https://www.gov.scot/collections/scottish-surveys-core-questions/).
Smoking - Scottish Survey Core Questions
SSCQ results are published with specific 95% confidence intervals, which account for the varying designs of constituent surveys. Confidence intervals provide a measure of the accuracy of point estimates, and should be considered when quoting statistics from this source. More information is provided in the SSCQ annual report.
Current smokers by Current smokers by tenure, household type, age, sex and disability. The Scottish Survey Core Questions is an innovative project drawing together multiple household surveys to provide a large sample for subnational analysis.

The preferred source of statistics for time series at Scotland level before 2015 was the Scottish Household Survey. Comparisons of results between SSCQ and the SHS are provided in the SSCQ annual report. By pooling three surveys, SSCQ provides results at sub-national level that are often impossible with a smaller sample. Earlier results (2012-2015 and 2014-2017) from the survey are presented for Electoral Wards using the 2007 to 2016 boundaries. These may not be comparable to other datasets which use the current Electoral Ward boundaries. Details on live and archived geographies can be found in the [Standard Geography Code Register](https://www2.gov.scot/Topics/Statistics/sns/SNSRef/StanGeoCodeRegister).
Further information on the methodologies used to produce these statistics can be found in [the SSCQ technical reports](https://www.gov.scot/collections/scottish-surveys-core-questions/).
Results from the SSCQ are generally published a year after the conclusion of fieldwork period, and after results from the constituent survey are published.
The pooling of Core Questions results in an annual sample of around 20,000 respondents, providing unprecedented precision of estimates at national level. This sample size enables the detailed and reliable analysis of national indicators by protected equalities characteristics such as ethnic group, religion, country of birth, sexual orientation, age, and gender. Further variables are education level, economic activity, tenure, car access and household type. Multi-level analysis is available on request.
