Southern California is a region of California, comprised of the Los Angeles and San Diego metropolitan regions.
Southern California is most easily divisible by counties, from North to South:
English is the official language of California and is the predominant language in Southern California. However, Spanish is also spoken by large Hispanic populations and it is not uncommon in Southern California to see store and street signs written in both English and Spanish. Chinese, Tagalog, Japanese, Hindi, Korean, Vietnamese, and Cambodian are also spoken by various immigrant groups.
Most Southern Californians drive their personal cars to get around. Just listen to the evening traffic reports and you'll get an idea of how many cars are driven in the area each and every day.
The metropolitan regions of Southern California consists of many small cities that run into one another. It can be confusing and you can get lost very easily if you do not have a map, even with detailed directions. A Thomas Guide, which contains detailed maps of all neighborhoods, is a useful tool if you plan on doing any driving in Southern California. This book can be found in local stores and bookstores.
Mass transit is available throughout the area, with many connecting together at shared stops. The regional commuter train,MetroLink, connects many of the outreaching areas, where many commuters live, with Los Angeles and Orange County, where they work. This train system comes in handy when you need to get from one area to another, even with their limited schedule.
