Welcome to our community request system.

Here you can submit data questions and requests and we’ll connect you to someone on our team who can guide you to the answer.

Once your request is submitted, we’ll add it to our workflow. Then, the analyst fulfilling your request will reach out to you to clarify any details.

Thanks to the generous support of The Kresge Foundation, we are able to answer more data questions than ever. We will do our best to fulfill your AskD3 request free of charge, and will be sure to let you know if there’s a fee before we get started.


Frequently Asked Questions

How can I share my data with D3?

We’re always happy to take delivery of a new dataset! 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.

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

Thank you for your attention to detail! We strive to have complete accuracy in all our data, and we welcome your feedback. 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.

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?
