National Service Territories
In 2020, National created a restructuring proposal, called the Churchill Plan (pdf). Among other details, this plan recommended that the BSA organizational structure of regions, areas, and sections should be redrawn as 16 "National Service Territories".
As of the May 2021 National Annual Meeting, these NST are official. And while National stresses that these maps are a continuous work in progress, these maps are the most recently made available.
In December 2021, as part of Project Magellan, National reorganized the Order of Arrow into two Regions: Eastern and Gateway, and a list of new sections was released. Since then, it appears that these two reorganizations for councils and lodges will continue separately. This is particulary interesting, as since the OA's full integration with the BSA in 1948, OA regions and areas have almost always been in lockstep with BSA regions and areas-- even to the detriment to lodge and section organizations.
