Abstract
The Origin of Movement (OM) series is unique data documenting the destination of state exports by subsector. A datum indicates the state an export begins its journey, not the production location (OP). Newer OM data have not been examined to determine if they represent OP. I describe the collection, dissemination, and limitations of the OM data. I perform diagnostic tests to asses how effectively the OM data represent OP. Results indicate the OM data are usable for OP, though there are idiosyncratic subsectors and states, and systematic differences distinguishing the OM from OP.
