Wisconsin: Aging Population Projection
Between 2010 and 2020, the population ages 65 and older will grow by 287,000 people.
In 2010, it was estimated that 119,900 persons had dementia.
By 2035, that number is expected to increase by 68% to 201,600.
The map on the left shows the percent of each counties population projected to be age 65 and older in the year 2015.
The percentages of individuals age 65 and older will change dramatically across the state.
The counties projected to have the largest percentages of individuals age 65 and older by 2015 are Vilas and Iron.
This population is expected to significantly increase in all counties over the next 25 years.
In Wisconsin, the population is rapidly aging in rural areas, and is most pronounced in the northern half of the state.
The increase is projected to occur at an above average rate in this portion of the state. These counties have moderate to high rates of poverty, based on U.S. Department of Agriculture data, as well as a higher level of health concerns per County Health Rankings.
NOTE: By 2040, 18 counties in Wisconsin are projected to have at least 33% of their total population ages 65 and older. Three of these counties are estimated to reach 40%.
