Finland in context: Street-network sprawl of new development

The level of street-network sprawl in new development in Finland rose steadily. To get a sense of how street development has changed in Finland, we can consider three of its most populous regions: Southern Finland, Western Finland and Oulu. Out of the three regions, Southern Finland and Oulu do not follow the same trend as the country. The level of street-network sprawl in new development in Southern Finland followed a zig-zag trend with an overall increase. The level of street-network sprawl in new development in Oulu peaked in 1991-2005.

The largest city in Finland is Helsinki, with a population of 968900 people. Taking into account the entire (i.e. aggregate) street network in Helsinki as of 2020, the overall level of street-network sprawl is 1.64, which is very well-connected. The level of street-network sprawl in new development in Helsinki followed a zig-zag trend with an overall increase.

Finland in context: Aggregate street-network sprawl

As of 2020, the city with the most disconnected street network in Finland is Tampere with an SNDi of 1.83, which is very well-connected. Conversely, the most connected city is Oulu with an SNDi of 1.44, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Oulu, Tampere.
