Frequently Asked Questions

How can I share my data with D3?

We’re always happy to learn about new datasets! If you have a file that you’d like to share with us, reach out with an AskD3 request. We’ll put you in touch with the most appropriate team member for that dataset. You can submit your AskD3 request by filling in the form above our FAQ!

What can I do if I find a discrepancy in D3's data?

Thank you for your attention to detail! Our goal is to provide the most accurate data possible, so community feedback is essential to our work. If you spot an inconsistency in any of our products, please notify us through AskD3. We’ll have a team member investigate the issue and follow up with you promptly.

How can I schedule an in-person appointment with D3?

D3 offers weekly virtual sessions through Co.act Detroit as part of Co.Lab Connect. Each week has a specific data focus. Learn more and register here! If you need a response sooner than our next virtual session, scroll up to fill out the above form, and we’ll get back to you as soon as we can.

Is there a cost for your services?

We fulfill many requests through AskD3, usually free of charge. For larger or repeated requests, we do charge a fee for our services. Please contact us so our project team can help you determine the best approach.

I'd like to use one of your products in my work. Do you have any use restrictions?

All data and maps on our website are available for use at no charge. Each dataset is licensed under a Creative Commons ShareAlike license. You can use our data if you follow the terms for attribution and sharing. When citing D3 data in your work, we ask that you include “Data Driven Detroit” after the primary source (for example, “U.S. Census Bureau, 2010 Census; Data Driven Detroit.”) For more details on citing D3, please read our Media Tools page.

Where can I learn how to use data?

We understand that data can be confusing and intimidating, and not everyone has had the opportunity to get foundational knowledge to use it in their work. We’ve assembled the learning resources we’ve created over the history of D3 in our Data Literacy resource to jump start what will be useful to know when using our data.
