 If an existing village's population surpasses 5,000 at a federal census, or if a village comes to have more than 5,000 resident registered voters, it is automatically designated as a city.Cities or villages may be within township areas; however, if a city or village becomes coterminous with a township, the township ceases to exist as a separate government (see Paper township).In Oklahoma, unincorporated communities are called villages and are not counted as governments.
