How San Francisco Transformed During the Gold Rush

1848‑1855: From ~1,000 to 25,000+ residents in months.

1. Demographic Explosion: Global influx (US, Europe, China, Latin America, Australia) – instant multicultural city.
2. Economic Boom: Supply hub for miners; banking, shipping, manufacturing, real estate skyrocketed.
3. Infrastructure Surge: Wharves, roads, telegraph, warehouses, water systems built at breakneck speed.
4. Lawlessness & Vigilantism: Gambling, saloons, crime → 1851 & 1856 Vigilance Committees.
5. Architecture: “Gold Rush” wood‑frame, corrugated‑iron buildings; later brick/stone for permanence.
6. Cultural Shift: Cosmopolitan, entrepreneurial, rough‑and‑ready identity forged.

Laid foundation for SF’s future as Pacific gateway and innovation center.
