The demographics of San Diego County include a diverse people by race, ethnicity, and nationality. Half of the population of San Diego County, California, lives in San Diego and Chula Vista.

Income

Despite having a per capita income that ranks between the Los Angeles metropolitan area and the San Francisco Bay Area, San Diego County has relatively few cities or CDPs with a both a high population and levels of income significantly higher than its state and the United States. The San Diego metropolitan area only has two populated places with over 50,000 inhabitants and a per capita income of over $40,000: the cities of Carlsbad and Encinitas. In contrast, the Los Angeles metropolitan area has 10 and the San Francisco Bay Area has 12. (See California locations by income.) Even when controlling for population, the San Diego metropolitan area has unusually few large areas with high per capita incomes compared to the state's other two major metropolitan areas. This is because much of the county's high-income residents are concentrated in the northern part of the city of San Diego, which is reported as one unit for most demographic purposes.

The county's largest continuous high-income urban area has the appearance of a triangle constructed from a first point on the northern edge of Carlsbad, a second point northeast of Poway and a third point on the southern edge of La Jolla in San Diego. The region is pictured to the right. It contains all or most of the cities of Carlsbad, Encinitas, Solana Beach, Del Mar, and Poway in addition to a substantial portion of northern San Diego.

Homelessness

Since 2015, the county has the fourth largest population of homeless individuals in the United States. Only New York City, Los Angeles County, California, and King County, Washington have larger homeless populations. Some of these homeless individuals are bused to the county, paid by other municipalities elsewhere. In 2017 and early 2018, the homeless population in San Diego County experienced an outbreak of Hepatitis A.
