Tijuana along with its U.S. neighbor San Diego form the largest metropolitan area on the U.S.-Mexican Border. Tijuana is a city in Baja California Norte, Mexico. It is located right across the border from San Diego, California, USA. Visitors can expect an ideal climate for most of the year.Economically, a growing middle class whose disposable income has fueled Tijuana's transformation into a modern city with a vibrant culture, a characteristic that has attracted many national and international businesses which had largely shunned the city before. Aside from the middle class, in Tijuana you can reasonably expect to find areas filled with richer people. Tijuana is a transit point for illegal immigration into the United States, as well as a common destination for any illegal Mexican immigrants deported from the west coast of the United States. As such, some areas are swollen with poor people with no roots in the city, who inhabit shantytowns. Apart from these poor migrants, Tijuana is one of the wealthiest cities in Mexico. Some (mainly residential) areas of the city reflect the significant number of wealthy people who inhabit the city.
Tijuana's growing reputation as a cosmopolitan city is justified. Not only is the city home to many people who have migrated from within the same country, as well as some native Mexican Indians, but it boasts an important amount of Asian residents, as well as Americans (mostly from neighboring San Diego who have been drawn to Tijuana by cheaper housing), and South Americans from Argentina and Uruguay, among others.
