Every city, same outline
Density, building ground, and shops use one GHSL urban-centre polygon. Axes start at zero. Click a city to open the pair page against San Francisco. Commute surveys stay in their own groups — they are not the same question.
People per km² and shops
Overture food and shopping places per km², clipped to that outline. Hollow dots: coverage is thin (mainland China), not empty streets.
People per km² and building ground
Satellite roof and pavement per resident (BUCAP15). High numbers are sprawl, not apartment size — extra floors do not count.
Car share, by survey
Each group is its own survey. Do not compare them as one number. Cities with no commute survey are left out of these bars — we don't know.
