Unincorporated Community
An unincorporated area is a region that is not governed by a local municipal corporation. Widespread unincorporated communities and areas are a distinguishing feature of the United States and Canada. Most other countries of the world either have no unincorporated areas at all or these are very rare: typically remote, outlying, sparsely populated or uninhabited areas. By country Argentina In Argentina, the provinces of Chubut, Córdoba, Entre Ríos, Formosa, Neuquén, Río Negro, San Luis, Santa Cruz, Santiago del Estero, Tierra del Fuego, and Tucumán have areas that are outside any municipality or commune. Australia Unlike many other countries, Australia has only one level of local government immediately beneath state and territorial governments. A local government area (LGA) often contains several towns and even entire metropolitan areas. Thus, aside from very sparsely populated areas and a few other special cases, almost all of Australia is part of an LGA. Un ...

York County, Pennsylvania
York County ( Pennsylvania Dutch: Yarrick Kaundi) is a county in the Commonwealth of Pennsylvania. As of the 2020 census, the population was 456,438. Its county seat is York. The county was created on August 19, 1749, from part of Lancaster County and named either after the Duke of York, an early patron of the Penn family, or for the city and county of York in England. York County comprises the York-Hanover, Pennsylvania Metropolitan Statistical Area, which is also included in the Harrisburg-York-Lebanon, Pennsylvania Combined Statistical Area. It is in the Susquehanna Valley, a large fertile agricultural region in South Central Pennsylvania. Based on the Articles of Confederation having been adopted in York by the Second Continental Congress on November 15, 1777, the local government and business community began referring to York in the 1960s as the first capital of the United States of America. The designation has been debated by historians ever since. Congress con ...

On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and locative information about more than two million physical and cultural features throughout the United States and its territories, Antarctica, and the associated states of the Marshall Islands, Federated States of Micronesia, and Palau. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives ...

Mason–Dixon Line
The Mason–Dixon line, also called the Mason and Dixon line or Mason's and Dixon's line, is a demarcation line separating four U.S. states, forming part of the borders of Pennsylvania, Maryland, Delaware, and West Virginia (part of Virginia until 1863). It was surveyed between 1763 and 1767 by Charles Mason and Jeremiah Dixon as part of the resolution of a border dispute involving Maryland, Pennsylvania, and Delaware in colonial America. The dispute had its origins almost a century earlier in the somewhat confusing proprietary grants by King Charles I to Lord Baltimore (Maryland) and by King Charles II to William Penn (Pennsylvania and Delaware). The largest, east-west portion of the Mason–Dixon line along the southern Pennsylvania border later became known, informally, as the boundary between the Southern slave states and Northern free states. This usage came to prominence during the debate around the Missouri Compromise of 1820, when drawing boundaries between slave ...
