SIGCHI Chapters are collections of people that are associated with SIGCHI who share a common location. Chapters are always geographical but may have a specific topic of emphasis. Similar to SIGCHI communities, chapters are groups of people, who, by banding together, can speak with a common voice within SIGCHI; can more effectively organize the activities that are of interest to them; and can obtain services that support their activities.
