Open Data Resources

This page is your one-stop shop for open data information including frequently asked questions, guides on how to use our data, how to suggest additional data and how to contact our staff.

What is Open Data?

Open data is machine-readable data (e.g. in a format that can be easily consumed and summarized by a variety of applications) that is free of charge and anyone is free to use, reuse, and redistribute it. Many cities and counties across the world provide open data to increase government transparency, accountability, and access to government programs and information.

City of Boulder’s open data is available online, in an open format, with no logins or fees required for use. The city’s open data team and data stewards are responsible for publishing and maintaining these datasets, per the 2017 Open Data Policy.

How to Navigate and Search the Open Data Site

Browse by Popular Topic

All datasets are assigned a category (e.g., arts and culture or government operations). On the open data catalog homepage, scroll down to the middle of the page and click on any popular topic category to browse datasets related to that topic.

Browse by Sustainability and Resilience Framework Category

All datasets are assigned a Sustainability and Resilience Framework category. On the open data catalog homepage, scroll down to the middle of the page and click on any of these categories to browse datasets related to that strategic framework area.

Browse by Department

Every dataset published on the open data catalog is sponsored or owned by one or more City of Boulder department(s). A list of datasets classified by department can be found at the bottom of the open data catalog homepage. Note that all city departments are listed here, but a given department may not have any datasets published yet.

Search by Keyword

The open data catalog homepage and all internal open data pages have a keyword search box.

Note that this keyword search is specific to open data pages and published datasets; it does NOT search the entire City of Boulder website and does NOT search within actual data files.

For example, if you search for ‘homeless’ you will be directed to datasets that have the word ‘homeless’ in the dataset title, description, and/or other tags. The search results will not include datasets that may only have the word ‘homeless’ within the actual data file.

Browse all Datasets

You can also browse the full open data catalog to see all available datasets. Use the filters on the left to narrow your search results.

How to Request or Suggest Data

How to Request Data or Information via CORA / public records request

The Colorado Open Records Act (CORA) requires that most public records be accessible to the public. Anyone can request information that the office possesses, and this can include raw or summary data on a City of Boulder program or activity. The open data program is not involved in CORA or public records requests. Visit Central Records for more information on the CORA request process.

How to Suggest a Dataset

The City of Boulder open data team is always adding new datasets and would love suggestions from the public for new topics and data. You can fill out our online form to suggest a dataset.

Please note that suggesting a dataset does NOT necessarily mean that city staff will be able to provide and post the data on our open data catalog. It does help us demonstrate public interest and demand to city departments and assists with our prioritization for data publishing pipelines. If you have a specific data request or urgent timeline, submitting a CORA/ public records request is the more appropriate course of action.

Partnering on a Data Project

The City of Boulder regularly partners with other public, private, and academic or research organizations for specific data analysis projects. The City’s Open Data Program and Innovation and Technology Department, can help facilitate these requests with interested city departments. Contact the open data team and provide more information about your proposed partnership or project.

Share Work Products using Boulder Open Data

We love to hear about how Boulder Open Data is used by the public! Please contact the open data team to share any analyses, visualizations, reports, or other work products that use our data. At a minimum we would like to share it with the relevant department(s) and data owner(s), and we may feature a link and summary on our Showcase page.
