b) Procedures for interviewing and filling the enumeration form:
When the interviewers visit every household, s/he needs to follow the procedure described below:
2. Counting the actual number of residents in the household
3. Filling out all the questions in the enumeration form
First, redefining the number of households:
In order to define the correct number of households in every house (or every apartment, room), interviewers should rely on the number of households in their household list. In addition, s/he needs to use the definition of a household and ask several questions to redefine the actual number, as below:
If the respondent is not sure or does not give a clear answer, then the interviewers can ask,
If the interviewer knows for sure that there is only one household, s/he can skip those questions.
After defining the number of households, interviewers ask the following questions to define the head of each household:
If the respondent cannot define it, interviewers can ask:
In the household, who can inform me about characteristics (age, education, occupation) of all household members?
Second, defining the actual number of residents in the household:
In order to define the actual number of residents in the household, interviewers need to use rules for defining interviewees and ask these questions:
2. Has anyone who used to live here already moved out of the household?
If yes, then ask: how long did this person move out?
b. If temporarily absent from the household (as in the rules for defining interviewees)-that person is a resident
c. Moving out of the household-skip
d. Less than 6 months: ask question 3
If yes, will this person continue to live here for more than 6 months?
No-temporary stay; skip
c) Filling the information for every person, method of interview, and filling out the enumeration form.
Who can be listed? All persons who are actual residents of the household, as defined in the section above.
Each person is listed in one column in the enumeration form. The household's head or the person in charge of giving the household's information is placed in the column "the 1st person". All other household members are listed in the rest of the columns of the enumeration form. The order should be ascending from the oldest person to the youngest person.
Before filling in the names of the head of the household on the "1st person" column, interviewers need to make sure if the person in the 1st column is eligible for the enumeration. If that person is not eligible (already moved, or is a policeman, or is in the army, etc.), the head can be substituted by the oldest member of the household, etc. In this case, the name of the head of the household in the column "the 1st person" is different from the name of the head in the middle top of the enumeration form.
2. Relationship to the head of household
 2 Husband/Wife
 3 Child
 4 Father/Mother
 5 Grand child
 6 Other family relative
 7 Non family relation
Relationship with the head of the household is one of the seven given relationships above. Interviewers only need to fill in the corresponding blank box.
Head: If the interviewee is the head of the household, interviewer can fill in "x" on box 1 for the 1st person column.
Husband/wife: If a person is the husband or wife of the head of the household interviewers fill in the 2nd box. Fill in the 2nd box even if they are not married, but they have lived together, including concubines. If the head of the household lives with 2 or more wives, all of his wives can be considered as his wives and fill in box 2.
Child: Children of the head of the household include biological children, adopted children, sons-in-law, daughters-in-law, and stepchildren.
Father/mother: Includes biological parents, adopted parents and parents-in-law of the head of the household.
Grandchild: If the interviewee is a grandchild of the head of the household, interviewers fill in box 5.
Other relatives: If interviewees have other family relationships, such as brothers, sisters, aunts, uncles etc., interviewers fill in box 6.
Non-relatives: If the interviewee is a servant, guest, friend, etc., without any family relationship to the head of the household, interviewers fill in box 7.
If the head of the household (or the substituted head) in column "the 1st person" is different from the name in the middle top of the enumeration form, interviewers should define relationship with the head of household with the 1st person.
Interviewers can easily identify the sex of the interviewees. In cases of young children or absentees, interviewers should ask the head of the household about their sexes. Do not guess any person's gender based on their names.
Interviewers should ask and fill out the actual month and year of birth for every person based on the solar calendar. Persons who have an incorrect date of birth in their legal documents (e.g. personal identification certificate, household registration, birth certification, etc.) can report their correct date of birth in the enumeration form.
If a person does not remember her/his date of birth in the solar calendar, but s/he remembers her/his age and date of birth in the lunar calendar, interviewers can check the calendar conversion table (in the appendix) in order to get the correct year of birth in the solar calendar.
In case that a person does not remember the month of birth but s/he knows her/his age by the lunar calendar, his/her estimated year of birth is, as follow:
If a person does not remember the date of birth or his/her own age or that for other household members, interviewers can ask several questions to find out estimated dates of birth.
If a person cannot remember his/her age or year of birth, interviewers can look at their appearance and ask them to estimate their own ages and use the calendar conversion table to fill in the year of birth by the solar calendar.
For children, if the interviewee does not remember his date of birth, interviewers can ask months of age and calculate the month and year of birth of the child.
Interviewers can use the information given by the head of the household to fill out the ethnicity column for the rest of the household members.
Children of a couple who does not have the same ethnicity, or an adopted child who does not have the same ethnicity than that of the adopting parents, or if any of the parents is a foreigner, respondents can define their own ethnicity if they are 18 years of age or older. If they are younger than 18 years old, their ethnicity can be defined either by the father or the mother.
For those who are naturalized Vietnamese, they need to fill out box 2 and write down their original nationality in the blank space.

If a person cannot read and write, interviewers fill out box 2 " 2 No"
If interviewers don't know for sure that a person can read and write, interviewers can ask two separate questions "do you know how to read?" and "do you know how to write?".

Persons who completed primary or secondary training curriculums but did not pass the final exam at each level of education are considered to complete the next lower grade at each level of education: the 8th grade of 12 or the 6th grade of 10 for primary school, or the 11th grade of 12 (or the 9th of 10) for secondary school.
Similarly, persons who completed training curriculum at each grade (such as the 5th grade of 12), but do not have passing scores for that class, would have the highest grade completed at the lower grade (e.g. the 4th grade of 12).
All other types of equivalent classes, such as at continuing education school, evening general education school, etc. are equivalent with classes at formal general education school.
