Challenges and opportunities of the 15-minute city to the poor and rich, black and white, from global south and north

The study discusses how far cities with different social and urban contexts are from a 15-minute city, including the challenges of sociospatial inequalities (by class and race) and residential segregation, and introduces a new algorithm to measure accessibility that consider both population and activities as endogenous variables.

In São Paulo, more densely populated, walking times to nearest activities are shorter, but the unequal distribution of social groups and school quality poses challenges for sustainable neighborhoods.

In London, while access to greenspaces is more evenly shared, the longer distances to daily activities limits active mobility.
