Urban planner: When a city loses population due to migration, property taxes in that city tend to rise  This is because there are then fewer residents paying to maintain an infrastructure that was designed to support more people  Rising property taxes, in turn, drive more residents away, compounding the problem
Since the city of Stonebridge is starting to lose population, the city government should ttherefore refrain from raising property taxes
If Stonebridge does not raise taxes on its residents to maintain its infrastructure, the city will become much less attractive to live in as that infrastructure decays.
