With their historically similar patterns of high and stable cohort fertility and high levels of gender equality, the Nordic countries of Sweden, Finland, Norway, Denmark, and Iceland are seen as forerunners in demographic behavior. Furthermore, Nordic fertility trends have strongly influenced fertility theories. However, the period fertility decline that started around 2010 in many countries with relatively high fertility is particularly pronounced in the Nordic countries. This raises the question of whether Nordic cohort fertility will also decline and deviate from its historically stable pattern. Using harmonized data across the Nordic countries, we comprehensively describe this period decline, and analyse to what extent it is attributable to tempo or to quantum effects. Two key results stand out. First, the decline is mostly attributable to first births, but can be observed across all ages from 15 to the mid-thirties. Large-scale fertility declines at ages above 30 have not been previously documented in these countries. Second, tempo explains only part of the decline. Forecasts indicate that the average Nordic cohort fertility will decline from two children for the 1970 cohort to around 1.8 children for the late 1980s cohorts. Finland diverges from the other countries in terms of its lower expected cohort fertility, below 1.6, and Denmark and Sweden diverge from Finland, Iceland, and Norway in terms of their slower cohort fertility decline. These findings suggest that the Nordic model of high and stable fertility may need to be updated, and call into question the broader theories linking fertility and gender equality.
