Corrected on 19 March 2021. The correction is indicated in red.

According to Statistics Finland's preliminary data, Finland's population at the end of December was 5,536,146. During 2020 Finland's population increased by 10,854 persons. The reason for the population increase was migration gain from abroad: the number of immigrants was 19,378 higher than that of emigrants. The number of births was 8,491 lower than that of deaths.

The preliminary total fertility rate grew slightly from the previous year, being 1.37 in 2020 (1.35 children in 2019). The total fertility rate indicates how many children a woman would give birth to, on average, during her life time if the birth rate remained the same as in the year on which the calculation is based.
