EC Unveils New Prototype for Defining Urban Agglomerations
The European Commission’s Joint Research Centre has unveiled a new prototype for defining and analyzing urban agglomerations across the EU. This approach maps functional urban regions based on economic, social, and mobility links, rather than administrative boundaries. The framework aims to improve the targeting of funding and the design of cross-jurisdictional policies, a common challenge in Dutch metropolitan areas.
This new prototype builds on decades of efforts to standardize urban definitions. The concept, previously called Larger Urban Zone (LUZ), originated in 2004 with Eurostat to create a harmonized "functional urban region" based on where a significant share of residents commuted for work. This definition was refined in 2011 in cooperation with the OECD and later adopted by organizations like the World Bank in 2020. The core methodology for Functional Urban Areas (FUAs) identifies a densely populated city and its commuting zone, defined as areas from which at least 15% of the employed population commutes into the city. The new prototype enhances this by using a grid-based model with population-weighted gravitational interactions, which allows it to function without relying on commuting data and to better represent both monocentric and polycentric urban systems. This approach is crucial for the EU's cohesion policy, which allocates funding to reduce regional disparities and support sustainable urban development. By providing a more accurate picture of urban systems, the new definition helps in the implementation of tools like Integrated Territorial Investments (ITIs), which combine funding for cross-sectoral projects in functional urban areas. For the 2021-2027 period, the EU has earmarked €24 billion for such sustainable urban development initiatives. In the Netherlands, with its polycentric urban structure and significant spatial pressures from population and economic growth, this redefinition is particularly salient. Dutch spatial planning, a decentralized system involving national, provincial, and municipal governments, constantly grapples with balancing housing, infrastructure, and sustainability in a densely populated landscape. The re-establishment of the Ministry of Housing and Spatial Planning in 2024 underscores the renewed focus on these challenges. The emphasis on functional rather than administrative boundaries directly addresses long-standing issues in Dutch cross-border regions, such as the Flanders-Netherlands area. Differences in planning cultures, legal systems, and administrative procedures have historically created barriers to integrated infrastructure and development projects. A standardized, function-based definition of urban areas can support initiatives aimed at overcoming these obstacles and fostering more coherent cross-border spatial development.
