It would be very surreal to see census reports like this:
Earth: Pop.=10 bil.
Luna: Pop.=300 (123 engineers/scientists, 70 residential, 117 miscellaneous)
Mars: Pop.=48 Scientists
Europa: Pop. = 25 Scientists* and 12 robots (Short trip)
lol I don't know. Seeing that in video games/movies is cool. It would be even cooler to know we have people living up there doing things.
