The SSCQ gathers survey responses from identical questions in the Scottish Crime and Justice Survey, the Scottish Health Survey and the Scottish Household Survey into one output. 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 key national estimates by ethnicity, sexual orientation, religion, age and gender, marital status, education level and economic activity, as well as tenure, car access and household type. SSCQ also enables a detailed sub-national analysis by local area, urban-rural classification and Scottish Index of Multiple Deprivation.
