Our first thank you is to the 14,000 men and women in Scotland who gave up their time voluntarily to take part in the surveys analysed here.
We are also grateful to the interviewers who conducted the surveys for the dedication and professionalism they applied to their work.
We would also like to thank Joan Corbett at the Scottish Centre for Social Research who patiently answered many questions on the data, and John D'Souza at the National Centre for Social Research who answered technical questions regarding weights.
Responsibility for all analyses and conclusions lies with the authors.
