A majority of the applications come from people who want to change their surname to something unique or take an old family name. Emilia Aldrin does research on surnames and says that it has become trendy to have a rare surname.
"Our society is becoming more and more individualized and this trend reflects that. It has become increasingly important to be your own person, to be your own trademark," Aldrin says.
To change your last name in Sweden you need to apply to the Swedish Patent and Registration Office.
