Urban green space is the share of a city's mapped urban area covered by vegetation.

• Higher percentages mean more of the measured urban footprint is green.
• The figure includes tree canopy and other vegetation, not just formal parks.
• The photo is a city clue. The answer is the city's green-space percentage.

A green city in this dataset can be a forested suburb, a park-heavy capital, or a boundary that simply includes more vegetation.
