Yes it's "just a data collection app".
You're talking about an org that, if your address is in the middle of a swamp, they will send someone by boat to find you.
They take collection and processing very seriously.
If you gave a startup 200 million or whatever, you'd have a pretty accurate census of internet connected people in the top 20 cities in the US. Oh, and a declaration of victory from the startup, plus 300 billion in market cap in the hope that they may actually be able to count everyone someday!
Somehow, i doubt you'd come up with something that can collect data well, know where to be focusing field representatives, etc with 600k+ field representatives in a reasonable and efficient manner.
Has anyone here tried to organize people,targets, and data in say a company twice the size of all of IBM? How did that go? :)
(the census is honestly relatively cheap. it costs about 50 bucks per person, total. Obviously, counting rural, etc areas is the majority of the cost)
The 2020 Census is going to be weird, too. Disadvantaged minorities, etc are statistically less likely to be counted[1], and especially given the climate in the US, counting immigrants is going to be especially hard.
[1] Which is why in the US, they democrats often try to pass rules around using statistical methods, and the republicans claim it requires actual enumeration
