San Francisco has a high standard of living. The great wealth and opportunity generated by the internet revolution drew many highly educated and high income workers and residents to San Francisco. Many poorer neighborhoods have become gentrified. Property values and household income have escalated to among the highest in the nation, allowing the city to support a large restaurant and entertainment infrastructure. Because the cost of living in San Francisco is exceptionally high, many middle class families have decided they can no longer afford to live within the city and have left to the suburbs of the San Francisco Bay Area.

Although the centralized commerce and shopping districts downtown, including the Financial District and the area around Union Square, are well-known, San Francisco also has a rich street environment featuring many mixed-use neighborhoods anchored around central commercial corridors to which residents and visitors alike can walk. They feature a mix of businesses and restaurants catering to the daily needs of the community and drawing in visitors. Some neighborhoods are highly gentrified, dotted with boutiques, cafes and nightlife, such as Union Street in Cow Hollow, and 24th Street in Noe Valley.

San Francisco has had an international character since its founding. Large numbers of immigrants from Asia and Latin America live in the city today. With 39% of its residents born overseas, San Francisco has numerous neighborhoods filled with businesses and civic institutions catering to new arrivals. In particular, the arrival of many ethnic Chinese, which accelerated beginning in the 1970s, complemented the already-established community based in Chinatown and has transformed the annual Chinese New Year Parade into the largest cultural event of its kind.
