Coterminous municipality in the context of List of municipalities in New York

A civil township is a widely used unit of local government in the United States that is subordinate to a county, most often in the northern and midwestern parts of the country. The term town is used in New England, New York, as well as Wisconsin to refer to the equivalent of the civil township in these states; Minnesota uses "town" officially but often uses it and "township" interchangeably. Specific responsibilities and the degree of autonomy vary in each state. Civil townships are distinct from survey townships, but in states that have both, the boundaries often coincide, especially in Indiana, Ohio, and Illinois, and may completely geographically subdivide a county. The U.S. Census Bureau classifies civil townships as minor civil divisions. Currently, there are 20 states with civil townships, including Indiana, Ohio, Illinois, Michigan, Iowa, Minnesota, Wisconsin, Missouri, Kansas, Nebraska, South Dakota, North Dakota, Pennsylvania, and West Virginia (in certain areas).

Township functions are generally overseen by a governing board (the name varies from state to state) and a clerk, trustee, or mayor (in New Jersey and the metro townships of Utah). Township officers frequently include justice of the peace, road commissioner, assessor, and constable, in addition to surveyor. In the 20th century, many townships also added a township administrator or supervisor to the officers as an executive for the board. In some cases, townships run local libraries, senior citizen services, youth services, disabled citizen services, and cemetery services, besides emergency assistance. In some states, a township and a municipality that is coterminous with that township may wholly or partially consolidate their operations.

Cairo (/ˈkɛəroʊ/ KAIR-oh, sometimes /ˈkeɪroʊ/ KAY-roh) is the southernmost city in the U.S. state of Illinois and the county seat of Alexander County. A river city, Cairo has the lowest elevation of any location in Illinois and is the only Illinois city to be surrounded by levees. The city is named after Egypt's capital on the Nile and is located in the river-crossed area of Southern Illinois. It is coterminous with Cairo Precinct.

Cairo is located at the confluence of the Ohio and Mississippi rivers, the largest rivers in North America, and is near the Cache River complex, a Wetland of International Importance. Settlement began in earnest in the 1830s and busy river boat traffic expanded through the 1850s. Fort Defiance, a Civil War base, was located here in 1862 by Union General Ulysses S. Grant to control strategic access to the rivers and launch and supply his successful campaigns south. The town also served as a naval base for the Mississippi River Squadron to pursue the Anaconda Plan to win the war. Developed as a river port, Cairo was later bypassed by transportation changes away from the large expanse of low-lying land, wetland, and water, which surrounds Cairo and makes such infrastructure difficult, and due to industrial restructuring, the population peaked at 15,203 in 1920, while in the 2020 census it was 1,733.

Kiryas Joel (Yiddish: קרית יואל, romanized: Kiryas Yoyel, Yiddish pronunciation: [ˈkɪr.jəs ˈjɔɪ.əl] ; often locally abbreviated as KJ) is a village coterminous with the Town of Palm Tree in Orange County, New York, United States. The population was 32,954 at the 2020 census, approximately 5% of the estimated 712,000 population of the Kiryas Joel–Poughkeepsie–Newburgh metropolitan area. The vast majority of its residents are Yiddish-speaking Hasidic Jews who belong to the worldwide Satmar sect of Hasidism.

According to the Census Bureau's American Community Survey, Kiryas Joel has by far the youngest median age population of any municipality in the United States, and the youngest, at 11.4 years old, of any population center of over 5,000 residents in the United States. Residents of Kiryas Joel, like those of other Haredi and Orthodox Jewish communities, typically have high birth rates, and this has driven rapid population growth. According to 2020 census figures, the village has a high poverty rate with about 40% of the residents living below the federal poverty line. It is also the place in the United States with the highest percentage of people who reported Hungarian ancestry, as 18.9% of the population reported Hungarian descent in 2000.

Cairo Precinct is located in Alexander County, Illinois, United States. As of the 2020 census, its population was 1,733. The precinct is coterminous with the city of Cairo.
