I would like to see the ratios of retirees in those numbers. In my small city in Wisconsin, we are actively advertising to retirees in high rent areas. I moved up from Chicago because the rent was cheaper. The city is building large 55+ apartment buildings all over our downtown area, and surrounding areas. The one group that has money, and doesn't need a job, is the elderly.
A woman in my building was moving in from San Francisco. She had been paying $3200 for a tiny 1 bedroom, and snagged a brand new large 2 bedroom for $1400 (with underground heated garage and exercise room) here. We have been having a lot of people from Phoenix move here.
It is the same for the city an hours drive away. I went to their downtown. The downtown has stores all geared to upscale elderly. 55+ apartment buildings and condos all geared to elderly. YMCA, fitness gyms, and urgent care within blocks of the of the downtown.
We are, also, listed as one of the best places to move because of climate change. Towns and cities are actively fighting each other over the elderly. A small town, about 2.5 hours north of me, turned an old high school into a retirement apartment building. I could have rented a huge 2 bedroom for less than $900. 1 block walk to supermarket, library, etc. These towns recognize that it isn't about getting high rent money; it is about getting us to spend the savings at the stores and restaurants.
If you don't need a job, then you can move anywhere.
