There are significant differences in county identification between states and regions in various countries, including the United States. In the U.S., for instance, counties are administrative divisions within states, but their roles, sizes, and functions can vary widely depending on local laws and traditions. https://whatcountyamiin.org/
Some states have a large number of counties, each relatively small in geographic size and population, while others have fewer counties, often larger in size and population. Additionally, the naming conventions for counties can vary, with some named after geographical features, historical figures, or Native American tribes.
