Cities such as Zurich and Dublin found to have key services accessible within 15 minutes for more than 95% of residents

When Luke Harris takes his daughter to the doctor, he strolls down well-kept streets with “smooth sidewalks and curb cuts [ramps] for strollers at every intersection”. If the weather looks rough or he feels a little lazy, he hops on a tram for a couple of stops.

Harris’s trips to the paediatrician are pretty unremarkable for fellow residents of Zurich, Switzerland; most Europeans are used to being able to walk from one place to another in their cities. But it will probably sound like fantasy to those living in San Antonio, Texas. That’s because, according to new research, 99.2% of Zurich residents live within a 15-minute walk of essential services such as healthcare and education, while just 2.5% of San Antonio residents do.
