Like we have “largest city” lists,

• most people would think largest city means most populous,
• but some people interpret it as city area,
• so in the former case Mexico City would be the “Largest” city in North america
• in the latter case, LA would be (i haven’t fact checked these, just roll with it)

Some cities are really populous, like Hong Kong, and it means people settle for very little living space just to have access to the opportunities there. Cities grow big largely on the basis of this principle - how many people are willing to slum it in one place together? And historically, the rich have done the opposite; when peasants are cramming themselves into as small a space as possible, the rich are building homes larger than entire villages.

So, to contrast a city of commoners and a city of wealthy people, one effective metric would be to look at the average footage (floor area) of peoples’ homes. Ideally divided by how many people there are, to have it on a per person basis.

I bet the results would be interesting. We’d find loads of places we didn’t know the names of, little hideaway towns which serve as getaways for the wealthy
