On the 31st of December 2019, the resident population in Portugal was estimated at 10,295,909 persons, 19,292 more than in 2018. This resulted in a positive crude rate of increase of 0.19%.
The population increase in 2019 resulted from an increase in net migration (from 11,570 in 2018 to 44,506 in 2019), since the natural balance remained negative (-25,214 in 2019). In 2019, therefore, there was a positive crude rate of net migration of 0.43% and a negative crude rate of natural increase of 0.25%, in the latter case for the eleventh consecutive year.
The net migration was positive in all regions NUTS 2, with greater expression in Área Metropolitana de Lisboa, Centro and Norte regions. These three regions, together with Região Autónoma da Madeira, were the only ones which contributed to the population increase in 2019.
In 2019, half of the people residing in Portugal were over 45.5 years old, which represents an increase of 4.3 years compared to 2009. Demographic ageing in Portugal, however, continues to rise with an ageing ratio, which compares the population aged 65 and over (elderly population) with the population aged 0 to 14 years (younger population), of 163.2 in 2019. Região Autónoma dos Açores recorded the lowest ageing ratio (97.2 elderly people per 100 young people), remaining the only region where the number of younger people exceeds the number of elderly.
