A division is part of the District Structure. Founders District in 2016-17 had ten divisions, and each division had roughly five areas. In 2017-18, there were seven divisions.
A division has a Division Director as well as other staff. A division has Division Contests and Division Council meetings.
Divisions have been voluntary, but in 2019 TI stated that no district had for many years chosen to do without divisions.
Through 2020, Founders District had for many years named their divisions with letters: A, B, C, etc. However, in the 2020-21 year, while divisions A, C, D, etc. exist, there is no division B. District 100, when it formed, used a different lettering system than A, B, C, etc.
