For the purposes of the Moody's Analytics estimated and forecast data products, we have established geography codes for metropolitan areas in Finland. Statistics Finland provides definitions in the Urban Audit data collection of urban statistics for European countries, to wit, metro areas are aggregates of municipalities (LAU 2, kunta). The four areas are:

• Helsinki
• Oulo
• Tampere
• Turku

Table 1 of 1. Metropolitan areas in Finland. We define each of our metropolitan areas as aggregates of LAU 2 municipalities.

Finland has a national geo code of IFIN, all codes for its geographic subdivisions use IFIN as a prefix, and all Moody's Analytics metro areas feature the letter "M." Each of the four areas is identified as IFIN(underscore)M(letter)(letter)(letter), and may be retrieved en masse by using the basket geo wild card IFIN_M^^^.
