The demographic situation in Portugal continues to be characterized by the decrease of the resident population, despite the increase of live births and immigration, and the decrease of emigration. The population decline has occurred since 2010, although it was mitigated in the last two years.
In 2015 there was a slight increase in the number of births (85,500 live births), for the first time since 2010. However, this increase was insufficient to counterbalance the number of deaths (108,511); the natural increase remained negative (-23 011) in 2015.
In what concerns migration flows, the net migration was less negative, with the increase of the number of immigrants and the decrease of the number of emigrants. However, the combined effect of these flows has resulted again in negative net migration (-10 481), as the number of immigrants continued to be lower than emigrants.
During 2015, 29,896 persons were estimated to have entered Portugal (as permanent immigrants), a rise of 53.2% compared with 2014 (19,516), and 40,377 persons have left Portugal (as permanent emigrants), a fall of 18.5% compared with 2014 (49,572).
As a result, the resident population was estimated at 10,341,330 persons, i.e. 33,492 less than in 2014, accounting for a crude rate of increase of -0.32% (-0.50% in 2014).
Also in 2015, the total fertility rate increased to 1.30 children (1.23 in 2014), slightly improving for the second consecutive year.
Life expectancy at birth in the 2013-2015 period was estimated at 80.41 years, and continued to be higher for women: 83.23 years compared to 77.36 for men.
In 2015 32,393 marriages took place in Portugal (915 more than in 2014). This number increased for the first time since 2000.
