Release Information


This is the complete expulsion or extraction from the mother's body, irrespective of the duration of the pregnancy, of a product of fertilization that, after separation, breathes or shows any other signs of life, such as a beating of the heart or umbilical cord or actual contraction of any muscle subject to voluntary movement, whether or not the umbilical cord has been severed and whether or not the placenta is retained.


The movement of people across a specified boundary for the purpose of temporarily or permanently changing his or her place of residence. Divided into international migration (migration between countries) and internal migration (migration within a country).


Comprises persons who, at the time census day - 00:00 hours on the day of reference - are at a dwelling even if they do not reside there, or who, even if they are not there at the time, arrive by 12:00 hours on that day.


The permanent disappearance of vital functions.


Portugal resident population estimates are developed based on the cohort-component method. Therefore, the trend of the crude rate of population over the last years is a result of variations of both components of population growth, namely the migratory component.

The natural growth rate follows a downward trend since 1970 and, in the same period, the migration growth undergoes large fluctuations. In the years near 1974 it rises considerably, which is associated with the decolonization process of former African colonies and consequently to the return of Portuguese residents in the former colonies to Portugal, reason why the year 1974 has the highest population increase, after a negative increase from 1970 to 1973.

 The source revises data on a yearly basis and generally revises data since the previous census when new census data is released.
