Helsinki region statistics API

The regional statistics interface enables the computerised retrieval of statistical data in Greater Helsinki’s Aluesarjat (in Finnish) statistical database in different file formats, such as XLSX, CSV, JSON and JSON-stat.

The Aluesarjat statistical database contains statistical time series on several regional phenomena. The statistics are mostly annual, the longest population series starting from 1962. The database consists of three entities: statistical area data of the cities of Helsinki, Espoo and Vantaa as well as municipal and regional statistics on Greater Helsinki and the Uusimaa region. ¨ The database provides the latest information available. Some data is updated once a year, some on a quarterly basis.

The statistics of the database are described in more detail in the data collections Aluesarjat and Historialliset tilastot.
