>A census literally counts every individual. I'm afraid that this isn't the case; a census is a best-efforts estimate. There are plenty of people missed for a variety of reason, everything from not wanting to be found, through to simple avoidance. Let alone filling out the forms incorrectly or giving dud answers to the army of amazing people trying to make sense of all the madness. Edit: realising the above has added to a long list of things that once upon a time I thought were hard-set facts, and nowadays I'm slowly losing my mind over. Coordinates, populated place boundaries, census counts + demographics... I mean, what _is_ an address? Incredibly painful to get to the bottom of that one, at least in the UK where the definition of an address will vary significantly by use case screams into the void
