San Francisco

The City and County of San Francisco - named for St. Francis of Assisi - is a major city in the state of California. It is situated on the northern corner of the San Francisco Peninsula, midway up the Pacific. The "City by the Bay" is California's only consolidated city-county. It is the state's smallest county also, with a land area of about 47 square miles. San Francisco is the fourth-most populated city in California and the 13th city with the most people in the United States. This is a highly densely-populated city (second-most among major American cities), with about 18,450 people for every square mile. Along with its surrounding locations, the city is also called the San Francisco Bay Area.

San Francisco is the major commercial, financial and cultural center in Northern California. It serves as the base of many notable corporations and financial institutions. Among the companies with headquarters here are Airbnb, Uber, Twitter, Mozilla, Craigslist, Levi Strauss & Co., Reddit, and Gap Inc.

This is arguably a very beautiful city. Its mild climate, cool summers, rolling hills, landmarks and architecture have contributed to make it a popular tourist location. Temperatures in the city neither get too hot nor too cold in summer and winter respectively. Mornings in San Francisco are typically foggy, which is why it is often called the "Fog City."
