The Scottish Household Survey (SHS) gives the peak age group for men voting in local elections as 60+ (79% voting). For women, it is 60-64 (84% voting). However, the SHS annual report (2003) states that overall more people say they voted (64%) than actually voted (49%).

56% of men and 52% of women aged 65-74 say they know who their local councillor is, compared with 36% of people aged 18-49.
