But your video doesn't show that? It's just shows high level aggregations. It doesn't say "homer simpson living at 123 evergreen terrace, springfield" is 47 years old, votes republican, earns $50.1k, and rates 3/5 on agreeableness.
"We could see where these people are on the map. if we wanted to drill down further, we could resolve the data to an individual level where we have close to 4000-5000 data points on every adult in the United States"
That seems more of a case of someone trying to hype up their product, than something that's actually real. What's likely actually happening is that they got a vaguely complete list of adults somehow (eg. voter rolls or DMV registrations), then the rest of the attributes are filled in using guesswork (eg. the name "Homer Simpson" probably implies he's white and male, the zip code he lives in implies he's middle class, etc.)
