Do you have regions with a very high proportion of retirees in your country?

Today national broadcasting company YLE released an article where you can check the proportion of retirees across municipalities.

I found it shocking that out of 308 municipalities in Finland there are 78 where majority of the population are retirees. In Ilomantsi, Hyrynsalmi and Rääkkylä, which are rural municipalities located in Eastern Finland, the proportion of retirees is over 60%.
