Parish and town councils vary enormously in size, activities and circumstances, representing populations ranging from fewer than 100 (small rural hamlets) to up to 100,000 (Sutton Coldfield Town Council). Most of them are small: around 80% represent populations of less than 2,500; and two thirds spend under £25,000 per year. They are generically referred to as "Local Councils", and most are affiliated via County Associations to the National Association of Local Councils (NALC), which represents their interests at a national level.
