Context
The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Finland, for both new street additions (left) and the aggregate street network (right).
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.
How do development practices in Finland fare in comparison to others in the world? Most recently in 2006-2020, street construction in Finland was the 23rd-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, street construction in Finland has become more disconnected. Finland ranked 46th in 1975, 19th in 1976-1990, 28th in 1991-2005 and 23rd in 2006-2020.
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.
The level of street-network sprawl in the aggregate network in Finland rose steadily. To get a sense of how the aggregate street network has changed in Finland, we can consider three of its most populous regions: Southern Finland, Western Finland and Oulu. Disconnectivity in the most populous cities in Finland follow the same country trend.
To date, Finland is the 28th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, the street network in Finland has become more disconnected. Finland ranked 46th in 1975, 33rd in 1976-1990, 28th in 1991-2005 and 28th in 2006-2020.
