Over the past ninety years, the BSA has utilized several different organizational structures for councils and lodges. In 1938, lodges were grouped first into fifteen, then eventually twenty-six areas. When the OA became fully integrated into the BSA in 1948, lodges were reorganized to match the twelve scouting regions.

In 1973, a new Section Operation realigned councils and lodges into six regions.

In 1992, four new regions were created: Central, Northeast, Southern, and Western.
