Present resident - For persons who are residents of the dwelling and were present in it on the date of the Census;

Absent resident - For persons who are residents of the dwelling and were temporarily absent from it on the date of the Census, such as:

a) Persons away on leisure or business;
b) Students at boarding schools or living in boarding houses, homes of relatives, etc.;
c) Those temporarily committed to sanatoriums, hospitals or other similar establishments;
d) Persons imprisoned but with legal proceedings still in progress, without final sentence;
e) Sailors at sea.

The persons specified above will be included as present nonresident where they are located on the date of the Census.
Members of the family group should not be included when they are in the places mentioned below, in which case they should be enumerated as present residents of the places where they are on the date of census.

a) Those permanently committed to sanatoriums, asylums or other similar establishments;
b) Those imprisoned and serving sentence;
c) Those who, due to their occupation, employment or other reason, must sleep away from home, such as soldiers at military bases, nurses living in hospitals, domestic employees living at employers' homes, etc.;
d) Workers, generally Northeasterners, who immigrate to the south in search of work on farms or in civil construction.

Present nonresident - For persons who are not residents of the dwelling but who are temporarily present in it on the date of the Census.
It should be noted that persons absent from their dwelling on the date of the Census will be enumerated twice: once at their usual dwelling, as Absent residents, and again as Non-residents present at [p. 26] the dwelling where they spent the night of August 31 to September 1. The National Census Service will eliminate the double enumeration when the calculations are processed. This information is essential, not only as an element of criticism and control, but also for special studies.
Two situations are exceptions to the criterion adopted: family groups that have two dwellings, one of which serves as occasional residence (summer home, country house, etc.), in which case the family group will be enumerated in only one of the dwellings, and those that own two residences, part of the family group living in one dwelling and part in another (as is frequent among ranchers who have younger children studying in the city), who will be enumerated pursuant to the following criteria:

a) All the members of this family group will be enumerated at the dwelling where the majority of the members are present on the date of the Census, and each one will be recorded in Question B as either a present resident or an absent resident;

b) At the dwelling where the minority of the family group are present, only the persons present on the date of the Census will be enumerated, recording each of them in Question B as present nonresident.
