Switzerland’s Urban Shift: How Cities and Surrounding Areas are Merging
New data reveals the increasingly interconnected nature of much of Switzerland with its cities – and why urbanization continues to progress here. This shift has both positive and negative consequences.
While Switzerland’s largest municipality, Zurich, with 450,000 inhabitants, doesn’t even rank among the 100 largest in Europe, let alone Geneva, Basel, or Bern, this only tells part of the story. Considering the reality of daily life, rather than political boundaries, paints a different picture.
Defining the Functional Urban Area
The European statistical agency Eurostat uses the metric of “functional urban area” to measure this interconnectedness. This metric is consistently applied across countries and provides a more precise assessment than indicators like “agglomerations” or “metropolitan areas.”
Early 2024 data shows that 5.4 million people in Switzerland live within these functional urban areas, an increase of approximately 250,000 since 2016. The Zurich urban area alone is home to over 2 million people, placing it among the 20 largest in Europe. These Swiss areas are also growing at a rate faster than the European average, according to a recent analysis by the Federal Statistical Office (BFS).
Beyond City Limits: Commuting and Connection
A functional urban area is defined by strong connections between surrounding municipalities and the core city. It includes locations where at least 15% of the workforce commutes to the core city. In Zurich’s case, this includes areas like Baden AG, Rapperswil-Jona SG, and Zug. Similarly, Thun BE and Burgdorf BE are considered part of Bern’s functional area, while Muttenz BL and Frick AG are linked to Basel.
For Basel, two figures are calculated: 585,000 within the Swiss part, rising to 850,000 when including municipalities in France and Germany. Geneva, including French communities, reaches approximately 900,000 inhabitants. This places Geneva and Basel within the top 50 urban areas in Europe.
A Historical Perspective on Swiss Urbanization
Compared to other European cities, Swiss urban areas are significantly larger than the core cities themselves. This is rooted in Switzerland’s history, which lacked the large empires and strong, representative capitals seen in places like Vienna or London.
Geographical factors and Switzerland’s decentralized nature also prevented the emergence of megacities. Large-scale incorporations of surrounding communities, often forced in other countries, were rare. When municipalities did join cities, it was typically due to financial necessity – examples include Kleinhüningen joining Basel in 1908, Bümpliz joining Bern in 1919, and several communities joining Zurich by 1934.
The Rise of the “Urban Sprawl”
Switzerland may not have large cities when considering political boundaries, but the reality is more complex. Around Zurich, a continuous settlement belt now houses nearly one million people. According to BFS, three-quarters of the Swiss population now lives in urban municipalities, compared to one-third a century ago. Switzerland is increasingly becoming one large urban area.
This “urban sprawl” is further illustrated by data from the EU’s “Copernicus” program. Within a 50-kilometer radius of Zurich’s city center, 3.8 million people live – more than in Munich, Vienna, or Prague, and only about 20% less than in Berlin or San Francisco.
Switzerland as Part of the “Blue Banana”
Other Swiss cities also boast impressive figures: Lucerne has 2.9 million within the same radius, Basel 2.4 million, St. Gallen 2.3 million, Geneva 1.9 million, and Bern 1.8 million. The proximity of these cities leads to some overlap in these figures.
Switzerland is part of the “Blue Banana,” a densely populated, 1,300-kilometer urban corridor with approximately 110 million inhabitants, stretching from northern Italy to the Irish Sea and encompassing metropolises like Milan, Brussels, and London. This region is one of the world’s most economically powerful.
Comparable regions include a 750-kilometer band along the US East Coast between Boston and Washington D.C. (53 million inhabitants) and the 1,200-kilometer Taiheiyō Belt in Japan (93 million inhabitants). These regions share common characteristics: prosperity and urbanization.
The Impact of Commuting and Infrastructure
The strong connections between core cities and surrounding areas, thanks to efficient S-Bahn and highway networks, mean many people live outside the core city but function and spend their leisure time there. This has both positive and negative consequences: core cities offer a disproportionately large range of cultural, gastronomic, and employment opportunities relative to their population, while many surrounding areas become “dormitory towns” and experience high traffic congestion.
This is reflected in commuting patterns. More people commute from surrounding areas to work or study in Zurich than commute to Vienna, a city 4.5 times larger in population. Dresden, with almost four times the population of Bern, has only 1.4 times as many jobs.
FAQ
Q: What is a “functional urban area”?
A: It’s a measure of interconnectedness between a city and its surrounding communities, based on commuting patterns.
Q: How is Switzerland’s urbanization different from other countries?
A: Switzerland’s historical lack of a strong central authority and its decentralized structure have resulted in a more dispersed urban landscape.
Q: What is the “Blue Banana”?
A: It’s a densely populated urban corridor in Europe, stretching from northern Italy to the Irish Sea, of which Switzerland is a part.
Did you grasp? The Zurich functional urban area is among the 20 largest in Europe, with over 2 million residents.
Pro Tip: When considering relocation within Switzerland, look beyond the city limits and explore the surrounding communities for potential housing and lifestyle options.
