The 15-minute city concept aims to make essential amenities reachable within a 15-minute walk or bike ride from home.

If effectively implemented, this could promote sustainable transportation, foster vibrant urban environments, and reduce vehicular congestion and emissions.

Population: 6.1M

Neighborhoods with higher amenity access also have higher 15-minute trip rates

Our research also highlights potential socio-economic challenges of the 15-minute city.
In lower-income neighborhoods, local living may increase segregation by limiting
exposure to socio economically diverse interactions.

Harness the 15-minute index to shape walkable, livable cities.
