Methodology
AlzOC utilized federal census data and adjusted the number of people aged 65 years or older in Orange County using the published County of Orange number of seniors. We then overlayed that number (497,346) with ethnicity, as stated in the federal census.
We applied widely published dementia prevalence figures from peer-reviewed studies indicating the percentage of people who experience a condition like dementia or mild cognitive impairment to the population data for Orange County.
Following this methodology, we extrapolated the number of people with some form of dementia in Orange County, the number of people with mild cognitive impairment (MCI), and, therefore, the number of seniors in Orange County with some form of cognitive impairment.*
*Disclaimer: these numbers are estimates using widely published and generally accepted prevalence and census figures. Gender and younger onset dementia or dementia occurring before 65 have not been factored into these figures.
