You can contact a dataset's owner with questions about the content or validity of a dataset. If you use the "Contact the dataset owner" feature, which is available on every dataset page, you'll be able to email them a message or question about their dataset and they can get back to you with a response if necessary.
To contact a dataset owner:
Open the dataset you have a question or feedback on.
Click on the "About" tab in the upper right.
Select "Contact Dataset Owner" at the bottom of the About sidebar.
A message will be sent to the data owner with the details you provide.
