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.

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).


4.1 and 4.2 Condition of migration

Question 4.1 identifies the number of people who lived in a state or country different than their current residence, that is, people who at some moment in their life have had a migratory movement, even having been for a short time.

If an informant answers yes in 4.1, circle code 1 and go to question 4.3, in the contrary case, circle code 2 and continue with 4.2.

When an informant declares never to have migrated, that is, has not lived in another federal entity or country, and the place of birth does not coincide with the entity of the interview, do not correct the written information and continue with question 4.2.

Vacation trips, commission work, visiting relatives or another cause are not considered migration, since it is not a change of residence.

When an informant doubts when considering whether the person who works or studies in another city migrates or not, ask the following questions in the order they are presented.

"If I ask (Name) where he or she lived, what would he or she say?" if the answer is the place to which they went to work or study, consider them migrants if contrary, register as non migrant.

[p. 96]

If this is not sufficient to know if a person left to live or not in this place, ask for the time absent from the household; if this is more or equal to six months, consider them migrants, if it is less do not register as migrant.

The phrase "even for a short time" refers to the movements made with the intention of leaving to live in another entity and for any reason have returned or changed residence to another entity or country and only lived there days, weeks or a few months.

Question 4.2 verifies that a person has always lived in the entity of the interview. When the answer is "yes," circle the corresponding code. In the case of the answer being "no," clarify with the informant about having lived in another entity or country. After doing this, correct question 4.1 and continue with 4.3.

If it is not possible to get the answer because the informant reiterates "does not know," circle code 9 and continue to 4.7.
