The only way we really know the answer to this question is by placing a lot of bias into our answer.
Edit: assuming a very US-centric dataset...
If the problem were the opposite it would also make sense to say that the data is too simple rather than too clean. That gets to what the article is saying; that all data collection is inherently biased.
“Our logs are stored as newline-delimited JSON objects.” No, it’s improperly escaped so it’s actually a JSON-like string of unknown character encoding.
“This is a postal code field.” Nope, it’s a user-generated string that occasionally converges on something approximating a postal code.
“This is the user’s IP address.” Well I clearly see localhost in here so unless folks are browsing the site from our servers, this is “sometimes” the user’s IP address.
"Don't call it Raw Data"
I would ask my manager to get me someone else.
