GCS Methodology
Scotland's Global Connections Survey is a sample survey, which was circulated to a representative sample of around 10,500 companies in 2006 who had operations in Scotland. The companies were selected using stratified random sampling from the Inter Departmental Business Register (IDBR).
For the 2006 survey, responses were received from around 3,500 companies (including nil responses). The information provided was supplemented with data from the ONS UK Monthly Production Inquiry, and was then grossed up to cover all companies on the IDBR using turnover. Adjustments were also made to the data for some industries based on other available information.
