Delft: a city of contrasts and a launchpad for knowledge and innovation

Delft. The city of Johannes Vermeer, Delft Blue and Museum Prinsenhof. A city brimming with culture. It is also unmistakably a student city: home to the largest technical university in the Netherlands and a lively nightlife. In recent months, Decisio examined the spatial‑economic and social situation of Delft. Curious about what we found? These are the three key conclusions.

Conclusion 1: Delft is a city of extremes

Delft is a city of contrasts. We all know it as a student city with many young people, educational institutions and student housing. The TU Delft campus and the city centre host several vocational colleges, universities of applied sciences and the university itself. More than 12,000 international students and employees live in Delft, around 12 per cent of the population and a higher share than in other student cities such as Utrecht or Groningen.

But Delft also has a relatively large population facing socio‑economic challenges. Residents have a lower disposable income than those in comparable municipalities. The housing market is another issue: compared with other major cities (the G44), Delft has a small share of owner‑occupied homes, a large social housing stock and high residential density. Families are scarce. Students who want more space after graduation can hardly find it in Delft. Anyone looking for a family home quickly ends up in neighbouring areas. Highly educated families move to places such as Den Hoorn (Midden‑Delfland) or Ypenburg (The Hague), but continue to rely on Delft for work, sport and social amenities.

Delft is not only a student city, it is also a city with socio‑economic challenges

This contrast creates pressure on liveability, space and municipal finances. Some neighbourhoods score very well on liveability, while others lag behind. These challenges are expected to grow in the coming years. One reason is that the city’s housing ambitions must largely be met within the existing urban area due to limited space. Most inner‑city development plans focus on (small) apartments, while demand within the city is higher for family homes. This tension, combined with Delft’s already scarce space, reinforces the imbalance between single‑person and multi‑person households.

Conclusion 2: Delft is the regional hub for work, shopping and education

From above, it becomes clear that neighbourhoods in surrounding municipalities are built right up to Delft’s borders. Data shows that Delft attracts more people from outside the city to work, shop and study than it sends elsewhere. Delft also plays a central role in sport, recreation, culture, religion and (business) tourism. Each year, at least 135,000 visitors come to sports facilities, swimming pools and cultural institutions.

Conclusion 3: Delft is a launchpad for knowledge and innovation, locally and far beyond

The study also examined the value of Delft’s ‘technological ecosystem services’: all activities on and beyond the campus that form part of the TU Delft knowledge cluster. Examples include the business clusters at Delfttechpark, the Biotech Campus and Delft Schieoevers. What is the value of this cluster of knowledge institutions and companies, and what role does Delft play?

First, the value. The cluster’s contribution consists of many elements: employment at major companies and knowledge institutions, the large student population and number of degrees awarded, startups, patents and innovations, and (foreign) investments. There is also indirect value, for example through spending by students, employees and visitors. One in five hospitality venues in Delft depends on TU Delft.

Delft’s role in this cluster is often described as the ‘backbone’: the starting point for knowledge, skills and innovations that help address societal challenges. Its impact extends far beyond the city. The cluster strengthens the regional and (inter)national business climate, for example by attracting companies to Delft or its surroundings, by the 2.5 million global users of TU Delft’s online courses (MOOCs), and by supporting the Netherlands’ ambition to remain a leading knowledge economy.

Looking ahead

The knowledge cluster has grown in recent years. Student numbers, degrees, patents and employment at educational institutions are all increasing. Third‑stream funding is rising as well. This growth is expected to continue, partly due to the National Growth Fund. Between 2021 and 2025, the Dutch government is investing €20 billion in programmes and projects that support long‑term economic growth. Fifteen Growth Fund proposals involving TU Delft have received nearly €4 billion in total. These resources are expected to increase the number of researchers and students, which in turn creates challenges for the municipality, such as providing space for facilities, housing and infrastructure. This requires significant effort but also presents major opportunities. The Netherlands must strengthen the commercialisation of knowledge, and Delft’s knowledge cluster plays a crucial role.

In the coming years, substantial funding will become available for innovation and its commercialisation. This represents both a major challenge and a major opportunity for Delft.
