Google points to this resouce as one of the top three sources it uses over here. "Google’s Knowledge Graph isn’t just rooted in public sources such as Freebase, Wikipedia and the CIA World Factbook," Google wrote.

Forum discussion at X.
Update: As expected, more pages are dropping out:
Here's the latest search visibility trending for The CIA World Factbook. It was shut down on 2/4. Again, it was a key source of information for Google's Knowledge Graph at one time. https://t.co/SkjkGBwljc pic.twitter.com/JXXxPRlIQh
