There are fewer divorces each year among all age groups, including those aged 60-69, according to Statistics Finland.
The trend among sexagenarians has been increasing for two decades until 2020, when it started to decline.
"The number of marriages has been declining for a long time, and gradually it has begun to affect the number of divorces as well," said Auli Hämäläinen from Statistics Finland.
Hämäläinen adds that divorce is rarer among those aged over 70, with no major changes over the last three decades.
Finns diverse relationships
Anna Rotkirch of the Family Federation of Finland says that there is a lower threshold to end a common-law marriage than a marriage, and that's evident among all age groups.
She points out that in the two decades leading up to 2020 life expectancy has had an impact on the number of divorces, as husbands are living longer.
"There are fewer widows, and long marriages are now lasting longer," said Rotkirch. "On the other hand, younger age groups have seen a steep rise in divorces and among 50-69-year-olds, around one in four have been divorced."
Relationships in Finland are more diverse in their character than those in many European countries, according to Rotkirch. In Finland there are more breakups, re-marriages, long-term singletons or relationships outside of common-law marriage than in other countries. And that is filtering through to older age groups too.
Middle age getting later
Rotkirch says 60-somethings are now undergoing a new stage of life known as "late middle age". 65-74-year-olds are now living longer, healthier lives, and they are also fitter and wealthier than previous generations.
"Many of them have the resources to do new things in their lives before they enter old age," said Rotkirch. "Naturally that is connected to the thought that 'is this really the person with whom I want to spend maybe another 25 years'."
