Hace poco y no hace mucho. El efecto en la medición de la migración por cambios en la duración de la residencia

Abstract

It uses the 1992, 1997, 2009 and 2014 data from the Dynamic Demographic National Survey (ENADID. It compares interstate migrants by place of residence one and five years before the interview. It verifies that the five years account exceeds three to four times the one year account. The quintuple is not reached because the return migration, i.e., people living in the same state five years before and at the moment of the interview, but residing in a different state one year before. The typical age-pattern of the internal migration rates occurs, but there are some irregularities towards the end of life in the one year estimates, because the sample size for one year is smaller than the lustrum sample. It is concluded that is better five years before than one in large sample surveys and censuses, in order to maximize the amount of migrants.
