How to estimate it

Fermi’s official “Napkin math”

The easiest place to start is the size of the city. Picture the dense, built-up part of Shanghai as a square maybe 35 kilometers on a side, so roughly 1,200 square kilometers. How many Starbucks per square kilometer? In a busy city you pass one every 10 minutes or so on foot, so call it about one.

Built-up Shanghai, 35 × 35 km
~1,200 km²
Starbucks per km²
× 1
1,200 × 1
≈ 1,200

Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
