Open data enables everyone to actively participate in urban development and make informed decisions. Open data improves transparency and helps to make the city more livable and sustainable.

For neighborhood initiatives and district groups:

Access to information about playgrounds, green spaces, traffic planning, or planned construction projects in your own neighborhood

For clubs and associations:

Use data on sports facilities, event venues, and infrastructure for club activities

For environmental and climate initiatives:

Environmental data, traffic figures, and land use for projects, actions, and campaigns

For citizen participation:

Fact-based discussions in citizen dialogues, participation procedures, and neighborhood discussions—supported by official data from the city administration

Open data is a valuable resource for research and teaching. It enables evidence-based studies, practical courses, and the development of data literacy.

Attention students! Our open data is ideal for:

• Bachelor's and master's theses on urban development, mobility, or demographics
• Semester projects and data analyses in data science, statistics, geography, or social sciences
• Research internships, empirical studies, and social space analyses

Code examples and tutorials

Jupyter Notebooks are available to help you get started with practical work using our open data sets.

Internship in the field of open data:

The Office for Statistics and Urban Research offers students the opportunity to gain practical experience in municipal data work—from the preparation of statistical information to publication on the open data platform. See the subpage Internship in the field of open data.

For teachers and researchers:

• Real data sets for courses
• Building data literacy by working with municipal data
• Basis for scientific publications
• Comparative data for regional and supraregional analyses

Are you researching or teaching with Wiesbaden data? We look forward to receiving your project reports!

We are looking for interested developers to implement an open data hackathon. The goal is to develop creative solutions using open data.

Please feel free to contact us using the contact details below, even if you are interested in a collaboration.

Possible applications:

• Data journalism articles on urban development, demographics, or transportation
• Fact-based reporting on local politics
• Visualizations and interactive graphics
• Comparisons and trend analyses over several years
• Investigative research using public data

Technical support:

Do you work as a journalist with data from Wiesbaden?

We welcome feedback on publications and are available to answer any questions you may have via the contact details listed below.

Open data is a catalyst for economic growth and innovation in our city. As part of Wiesbaden's smart city strategy, the open data platform supports the development of digital business models and innovative smart city solutions. Companies can use the data for:

• Location analyses and market research
• Developing smart city applications
• Infrastructure planning and forecasting
• Integration into their own digital services

Open data supports evidence-based decisions in administration and politics. Standardized, machine-readable data formats make cooperation between agencies and across administrative boundaries more efficient. Future-oriented topics such as sustainable urban development, climate protection, and future-oriented mobility can be addressed in a well-founded manner with concrete data.

The platform enables:

• Consistent data bases for decision proposals
• Transparent decision-making processes for urban society
• Efficient processes by avoiding data silos

Do you need reliable data for analysis, applications, or research? Our open data platform offers a growing selection of machine-readable data sets that you can search, download, and visualize directly.

The range of data is continuously being expanded in line with user needs. Your feedback helps us to fill gaps and add new topics.

Whether for research, development, or civil society projects, we make data accessible, understandable, and usable—including flexibly via our application programming interfaces (APIs).

Are you already using our data?

If you use open data from the state capital of Wiesbaden in an app, a research project, or another application, we would be delighted to hear from you via the contact options listed below. We are happy to link to your projects and show how open data creates added value in practice.

Practical examples of open data

Interactive tutorials are available to help you get started with our open data sets.

All published data sets undergo established statistical anonymization procedures. Personal or sensitive data is not published.

Wiesbaden is one of the first municipalities in Hesse to have a dedicated open data officer and established statistical anonymization procedures—this enables us to guarantee data quality and data protection.

Our goal is to gradually staopen data officer and established statistical anonymization procedures—this enables us to guarantee data quality and data protection.

Our goal is to gradually standardize data sets and metadata so that information is easier to find, compare, and reuse.

Open data licenses determine how published data may be used. Clear licensing creates legal certainty for users and enables innovative applications—from startup applications to journalistic research.

Why are licenses important?

Without a clear license, it is unclear whether and how data may be reused. Licenses clarify:

• Can I use the data commercially?
• Do I have to cite the source?
• Can I combine data with other sources?
• Can I integrate the data into my own applications?

Which licenses does Wiesbaden use?

The state capital of Wiesbaden relies on internationally recognized Creative Commons licenses, such as CC BY 4.0 (Creative Commons Attribution). This license allows:

• Free use, including commercial use
• Editing and further processing
• Combination with other data
• The only condition is that the source ("state capital of Wiesbaden") must be cited.

Other license types include CC0 (for maximum openness) and CC BY-SA 4.0 (for data sets that should remain open even when shared). Each data set on our platform is clearly labeled—you can find the license information directly in the metadata.
