Antioch, California, located on the San Joaquin River, is known as the Gateway to the Delta. It is the heart of Contra Costa County where many people live, work, and play. The town's population is over 100,00 with over 10 percent seniors age 65 and over.
Antioch has around 20 assisted living communities of significant size, along with multiple smaller residential care facilities. California regulates both types of residential community in the same way, through the state Department of Social Services Senior Care Licensing Division. As a rule, California's assisted living communities provide residents with 24-hour response from staff, as well as room and board, transportation outside the facility and help with various activities of daily living, such as dressing and personal care.
