The red part of the map is the city of Los Angeles, the largest city in Los Angeles County both in area and population. With a population of four million people, it is the second largest city in the United States. Los Angeles, the heart of Southern California, has recently become a world-class city. At the beginning of the 20th century, it was considered simply “a big town”.
Despite its natural deficiencies, it has established itself as an important center for trade, agriculture, tourism and industry. Los Angeles is known for its mild climate, extensive outdoor leisure and recreation, as well as for the special aura of celebrity associated with Hollywood. The lifestyle of Los Angeles residents (who call themselves Angelenos) is based on cars, idealizes single-family housing and favors informality. With notable exceptions, the horizon is mainly horizontal rather than vertical.
Los Angeles is a place of extraordinary ethnic and racial diversity, largely due to immigration, and like other cities in the world, reflects a growing gap between rich and poor. Los Angeles County is a region of thousands of square miles in Southern California, about the same size as Rhode Island. It consists of 88 cities (municipalities), with the largest being Los Angeles itself. The city has one of the largest high-speed road networks in the world and also has the highest per capita car population in the world.
The Los Angeles County bus network is GPS-enabled and works with major travel planning applications such as Moovit and Transit. California, which is the country's most populous state with the greatest passion for cars, planned its cities such as Los Angeles around cars to a greater extent than any other city, and now has the highest concentration of them all with more than 26 million people. Los Angeles and its surrounding area offer an eclectic dining experience that can't be found anywhere else. There are now emerging taxi apps such as RideYellow that offer a more convenient way to book a taxi in Los Angeles.
Since the city and county are geographically, culturally and economically intertwined, any consideration of Los Angeles must involve both entities. Despite its infamy traffic situation, people in other major cities may not be surprised to find that it ranks first as the most congested and polluted roads in the United States. Surprisingly, it doesn't hold the title of most chaotic car city because of its enormous highway infrastructure that allows residents of the Los Angeles area to continue their daily migration of more than 300 million miles. Population density around the metropolitan area varies widely from one person per square mile in mountainous areas to 50,000 per square mile near downtown Los Angeles.
Although most places are safe, there are some areas in Los Angeles County that are considered less safe than others.
