Real estate, building, and spatial information

The Population Information System contains data on buildings and residences. Real estate information contained in the Population Information System is maintained with the help of the cadastral register of the National Land Survey of Finland. The information from the Population Information System is utilised in various spatial data applications.

Building and dwelling information

The Population Information System contains data on buildings and residences. In international practice, building information is commonly referred to as the Building and Dwelling Register (BDR). Building information is maintained and checked in close cooperation with municipal building supervision authorities.

Information about construction projects is obtained from municipal building supervision authorities. Digital and Population Data Services maintains residence details related to persons and their respective residences. Cooperating with municipal authorities, we are also responsible for various changes and corrections to building information and maintaining of address and voting district information.

Cadastre (land register) authorities – district survey offices and municipal authorities – are responsible for matching buildings to the correct property by maintaining the building codes of the Population Information System.

Statistics Finland maintains municipal sub-area codes and business identity codes, which are submitted to the Population Information System at regular intervals.

Spatial information

The addresses, building codes and centre point coordinates of buildings form the basis of the Population Information System’s nationwide address information system. Using building and apartment codes, persons registered in the Population Information System can be linked with the centre coordinates of buildings and, using identifiers, buildings can be linked with other national base registers used in Finland. This enables the utilisation of the Population Information System in various geographical data applications.

For example the following information is registered in the Population Information System:
