96% of persons ages 65 and older in the United States are Medicare beneficiaries. According to the
2010 US Census, there were 40.3 million individuals ages 65 and older living in the United States
(Howden and Meyer, 2011). CMS estimates Medicare enrollment for its aged beneficiaries to be 38.8
million (excluding Puerto Rico and the Virgin Islands, but including if state unknown
https://www.cms.gov/MedicareEnRpts/Downloads/10Aged.pdf). Dementia status population estimates
use age at the time of drawing the sample (total weighted 65+ N = 38,152,000 and 71+ N =24,567,000).
2 Assigns 50% of nursing home residents to probable dementia and 50% to no impairment.
