Interviewer instructions
IV Migration
In this section the changes of habitual residence of the population from one entity to another or to a country other than Mexico are registered.
[graphic of the question from the census form]
Migration is understood to be a change in habitual residence from one entity to another or from one municipality (delegation) to another (internal migration); also from one country to another (international migration).
This section contains two focuses described below:
To investigate the state and international migration (number of people who came to or left Mexico), based on the previous place of residence (questions 4.1 to 4.5).
To know the place of residence on a set date (November 1990) and therefore the migration at the municipal and state level as well as international immigration (questions 4.6 to 4.7).
4.4 Time of previous residence
It is the time that a person lived in the entity or country declared in question 4.3.
[p. 98]
The notations in this question are only made in months or years. When the answer is in years and in months, write down only the years in the corresponding space; for example, if an informant reports that a person has lived in the previous entity one year and six months, write down 01 in column 4.4B.
If they declare the time only in months, write it down in 4.4A.
In cases in which the answer is 12 months or more, convert it to years and write it down in 4.4B.
When there is doubt, clarify that it refers to the time of living in the state or country declared in 4.3.
If a person lived less than a month in a previous place, write 00 only in the column of months (4.4A).
When an informant does not remember the time of previous residence, guide by helping as in the following example:
A person is 31 years old and born in Mérida, Yucatán, who at six years old changed place of residence to the place of the interview (entity of Jalisco).
Interviewer: How many months or years did José live in Yucatán?
Informant: Well, he came here when he was six years old.
Interviewer: Before living in Jalisco, did he live in another entity or country?
Informant: No.
Interviewer: Then José lived in Yucatán for six years.
Informant: Yes, that's it.
Also, if after investigating, the time of previous residence cannot be determined, write down 99 in column 4.4A.
