The number of North Dakota residents 65 and older with Alzheimer’s disease is projected to grow from 15,000 in 2020 to 16,000 in 2025, a 6.7% increase — the lowest increase of all 50 states.

48. Missouri (tied)
> Projected increase in adults 65+ with Alzheimer’s disease, 2020-2025: 8.3% (from 120,000 to 130,000)
> Pct. of population 65+: 16.5% — 21st highest (total: 1,006,725)
> Pct. of 65+ pop. with Alzheimer’s disease: 11.9% — 19th highest
> Avg. retirement income: $23,657 — 11th lowest

Missouri is tied with Wisconsin for the second-lowest projected increase in the number of older adults with Alzheimer’s disease in the next five years, at 8.3%. Age is the biggest risk factor for the disease — the vast majority of those diagnosed are 65 and older. Retired older adults in Missouri with the disease may struggle to afford care as the state’s average retirement income of just under $24,000 is one of the lowest in the nation.

48. Wisconsin (tied)
> Projected increase in adults 65+ with Alzheimer’s disease, 2020-2025: 8.3% (from 120,000 to 130,000)
> Pct. of population 65+: 16.5% — 22nd highest (total: 953,571)
> Pct. of 65+ pop. with Alzheimer’s disease: 12.6% — 9th highest
> Avg. retirement income: $24,064 — 15th lowest

Wisconsin is one of just three states in which the number of people aged 65 and older with Alzheimer’s disease is projected to increase by less than 10% between 2020 and 2025. Though the pace of increase is slower than it is nationwide, the share of 65 and older state residents with the disease is already fairly high at 12.6%, the ninth highest share in the nation.

47. New Jersey
> Projected increase in adults 65+ with Alzheimer’s disease, 2020-2025: 10.5% (from 190,000 to 210,000)
> Pct. of population 65+: 15.9% — 23rd lowest (total: 1,410,285)
> Pct. of 65+ pop. with Alzheimer’s disease: 13.5% — 3rd highest
> Avg. retirement income: $30,400 — 12th highest

New Jersey residents 65 and older are more likely to have Alzheimer’s disease than those in all but two other states, with 13.5% living with the disease. This high percentage is projected to increase by 10.5% in the next five years, one of the lowest increases among states, with the number of 65 and older residents with the disease growing from 190,000 in 2020 to 210,000 in 2025.

46. Iowa
> Projected increase in adults 65+ with Alzheimer’s disease, 2020-2025: 10.6% (from 66,000 to 73,000)
> Pct. of population 65+: 16.7% — 16th highest (total: 525,522)
> Pct. of 65+ pop. with Alzheimer’s disease: 12.6% — 11th highest
> Avg. retirement income: $22,021 — 4th lowest

The number of adults 65 and over in Iowa with Alzheimer’s disease is projected to increase by 10.6% from 2020 to 2025 — the fifth lowest increase of all states. Iowa’s retirement income of $22,021 is lower than that of all but three other states, which may make it more difficult for those with Alzheimer’s disease to afford the care they need.
