What about counting institutionalized people in places like nursing homes and prisons? How do you count people in cars with multiple occupants? How do you know who’s a resident any who’s a foreign visitor?

I wonder, census doesn’t, and can never, be exact, it is about allocating resources to support people using infrastructure.

We'll need an agency of people inspectors, authorized to enter residences and institutions to count people.

If we hire everyone to be a people inspector we can use the employment records as the census.
