As of 1991, the Swedish church ceased to be in control over the civil authority information. The tax authorities became the leaders of the organization of data. After 1991, the computer was used to further development the population registration, making it more easily accessible to researchers and the public.
Updating the tax authorities regarding a birth, marriage, death or residence change is not solely on the responsibility of the person. The postal office, civil authorities, hospitals and the National Land Survey office all update information about the population to the tax authorities. When a birth occurs, the hospital notifies the parents based on their address on file. The child’s name and any other pertinent information are then returned to the tax authority. The parents then are provided with the child’s personal identification number.
The system is organized in such a way to guarantee strong accuracy, as it is not merely the individual providing their information to the tax authority. Multiple organizations are involved in updating the taxc authority to provide accurate and up-to-date information about residents of Sweden.
In addition, the information is updated daily from the tax authorities to the Notification Registration which would then update elections offices, the church, the police, insurance organizations, etc. Quality checks of the information are conducted to push for accuracy.
For those who are not native Swedes, their information is also recorded in the population registers. Anyone who is residing in Sweden for an extended period of time is then registered.
The quality of the records is very high due to them being centralized and continually monitored.
