The dependency ratio has been falling in all Wisconsin jurisdictions, because as populations age, the number of dependents 65+ grows relative to the working-age population.
Polk and Burnett Counties have particularly low ratios, with Burnett approaching the point at which for every person in their prime working years (20 – 64 years old), there is one who is under 20 (and likely still in school) or 65 and older (and likely retired).
Pierce and St. Croix counties continue to have slightly stronger dependency ratios than the state, however, their ratios are falling closer to the average for Wisconsin.
The dependency ratio in Minnesota and Washington County have been declining slowly over time.
Chisago County’s dependency ratio has had a slower decline than the rest of the state; the county now has a higher ratio (1.46) compared to Washington County and the Minnesota average, even though its dependency ratio was lower than both in the first year of this dataset (2009).
For Chisago, Pierce and St. Croix counties, there were over 40% more workers than dependents in 2022.
For Polk County there were almost 30% more workers than dependents in 2022, but only about 5% more in Burnett County
