The city reform that has made city government more politically representative of its residents is the single-member district elections of council members. This system divides the city into smaller districts, with each district electing one council member to represent them. This ensures that each district has its own representative who understands and advocates for the specific needs and concerns of that area. By having representatives from smaller districts, the reform helps to prevent the concentration of power in the hands of a few individuals or groups, allowing for a more diverse representation on the council. Additionally, it encourages accountability, as council members are directly elected by the residents of their district and can be held responsible for their actions and decisions. Overall, single-member district elections promote fair and equitable representation of the city's residents and their interests.
