Each year, the study was undertaken through the monthly inclusion of a set of questions in the Scottish Opinion Survey, the consumer omnibus survey operated by TNS. This methodology ensured that a representative sample of around 1,000 members of the Scottish adult population (aged 16 years and over) was interviewed each month. While some questions were inserted into the survey every month, others were asked every second or third month, on a rotating basis. The survey was completed in 2013 and will be replaced by Scotland's Nature and People Survey [SPANS], which is likely to use a similar methodology and set of questions and indicators [Measuring Participation 2013). An indicator framework was developed as a basis for defining the scope of the project, reporting of headline findings, and to aid project management Thirty quantitative indicators are covered by the report, which are distributed between the seven themes.
