San Francisco

Despite the panicky (and even warranted) headlines, San Francisco is experiencing a renaissance fueled by AI innovation and bold urban reinvention. After weathering pandemic‑era commercial vacancies, the city’s recovery is gaining momentum through adaptive strategies now transforming its downtown core – driven by the city’s #1 ranking in our Business Ecosystem subcategory – and #2 in Economic Output.

New Mayor Daniel Lurie has recently announced ambitious initiatives – from a Breaking the Cycle plan to address homelessness and addiction to his Family Zoning Plan to reform neighborhood zoning and add up to 36,000 new homes by 2031, dramatically reshaping San Francisco’s urban fabric (already ranked #4 for Standard of Living). The city is consistently rolling out daring bike and pedestrian infrastructure like few other U.S. cities. Transit is also growing, with BART upgrades ranging from downtown escalator replacements to tap‑and‑go Clipper payments that ease commutes. The Top 5 global Air Quality ranking won’t protect itself.

The tech sector remains the city’s economic engine: Bay Area start-ups attracted $90 billion in venture capital in 2024 – 57% of all U.S. VC funding. The #6 University ranking (led by Stanford) ensures a talent pipeline to keep the future-defining innovation in town.
