In 2015, Alzheimer’s disease was the sixth leading cause of death in the United States and third leading cause of death among Californians and San Diego County residents. An estimated 84,405 San Diegans age 55 and older were living with ADRD, accounting for 11% of the age 55 and older population. In 2015, more than 35,000 San Diegans age 55 years or older were discharged from the emergency department (ED) or hospital with a mention of ADRD in their diagnoses. Assuming current trends continue, by 2030 over 115,000 residents age 55 and older will be living with ADRD, a 36.5% increase from 2015.

To help show this distribution, the maps below provide a visual representation of the projected increase of residents 55 and older, by sub regional area (SRA),  estimated to be living with dementia from 2015-2030.
