The enumerator was instructed to enumerate every living person whose usual place of residence was in their district, including persons temporarily absent. These persons were to be marked with “Ab” after their names. There were a few exceptions to that rule, however.· Military personnel were enumerated as residents of the place where they were stationed whereas members of their families were enumerated at the place in which they resided.
· Officers of merchant vessels under the American flag were enumerated at their homes on land.
· The crews of American merchant marine vessels were enumerated as part of the population of the port from which the vessel operated.
· Members of the household attending the Military Academy at West Point, the Naval Academy at Annapolis, or any other training school operated by either the War Department, the Navy Department, or the United States Coast Guard were enumerated as residents of those institutions.
· Student nurses away from home were enumerated as residents of the hospital, nurses’ home, or other place in which they lived while receiving their training.
· Inmates of a mental institution, nursing home, home for the blind and deaf, soldiers’ home, reformatory, prison, home for orphans, or any other institution in which the inmates may remain for long periods of time were enumerated as residents of the institution.
· Prisoners of jails were enumerated at the jail no matter the length of the sentence.
· Hotels, tourist or trailer camps, missions, and cheap one-night lodging houses (flophouses) were enumerated as of the night of April 8. All residents of those places on that night were enumerated on separate sheets numbered serially beginning with 81 so that the numbers would not overlap the numbers assigned to schedules used for persons enumerated in regular order.
