40. Illinois
> Projected increase in adults 65+ with Alzheimer’s disease, 2020-2025: 13.0%
> Pct. of 65+ pop. with Alzheimer’s disease: 12.1% (22nd highest)
> Pct. of population 65+: 14.8% (12th lowest)

The number of older adults with Alzheimer’s disease is projected to increase from 230,000 in 2020 to 260,000 in 2025. This 13.0% increase is lower than in all but 10 other states and is due at least in part to the relatively low share of older adults in the state. Roughly one in five Illinois residents who retired moved out of state, according to a National Movers Study. Just 14.8% of the state’s population is 65 or older, the 12th lowest share in the nation.
