Earlier quoted context omitted.
Furthermore, the 80% urban stat from the US census gets routinely misinterpreted. Just going through some property line details with a couple neighbors on collectively about 75 acres plus adjacent conservation land. The census considers this urban. And, as you say, Urban != dense city downtown.
yes, the cutoff for "urban" to not is 2000 housing units in an area. I don't consider that urban, 2000 homes is a decent "town". This is just "othering" of people who live more than 25 minutes from a metro which is what i consider "urban". i am 25 minutes from my nearest metro, and the metro population is smaller than the city i grew up in in california, population-wise. my point is, talking about Berlin and then car…
So a lot of people tend to translate 80% urban into 80% cities which is manifestly not true, and even less dense cities.
