The total fertility rate is the number of live births per woman of childbearing age. 1,5 children per woman is a critical level of fertility rate. If fertility is below this level the proportion of elderly in the population and the dependency ratio increases. 2,1 children is considered to be the level where the population increases without support of immigration. The fertility rate has seen a general decline in the Nordics since 2010. Iceland had the highest fertility rate of the Nordic countries for a long period of time, but has now seen Sweden take over this position.
Mean age at birth of first child
Increases in women's education and labour market participation are possible explanations for postponing parenthood to an older age. In all Nordic countries except Iceland the mean age of mothers at the birth of their first child is between 29,3 and 29,5 years. In Iceland, the mean age of mothers was 28,2 years in 2018.
