Distribution of birthdays per calendar year

Distribution of birthdays over the calendar year. The data originated from the Population Information System and the selection was made on 25 June 2019. It is important to note that during the years, the first days of the months have also included birthdays for people whose birthdays are unknown. This has been the case, for example, when refugees have arrived in Finland without proof of identity. In some cases, the date of birth of a person registered in the Population Information System is based on an assessment by a foreign authority. The data cover all persons living on 25 June 2019 from the Population Information System.
