Anatolia, also known as Asia Minor, is a large peninsula or a region in Turkey, constituting most of its contemporary territory. Geographically, the Anatolian region is bounded by the Mediterranean Sea to the south, the Aegean Sea to the west, the Turkish Straits to the north-west, and the Black Sea to the north. The eastern and southeastern boundary is either the southeastern and eastern borders of Turkey, or an imprecise line from the Black Sea to Gulf of Iskenderun. Topographically, the Sea of Marmara connects the Black Sea with the Aegean Sea through the Bosporus strait and the Dardanelles strait, and separates Anatolia from Thrace in the Balkan peninsula of Southeastern Europe.

A central bank, reserve bank, national bank, or monetary authority is an institution that manages the currency and monetary policy of a country or monetary union. In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base. Many central banks also have supervisory or regulatory powers to ensure the stability of commercial banks in their jurisdiction, to prevent bank runs, and in some cases also to enforce policies on financial consumer protection and against bank fraud, money laundering, or terrorism financing.
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage.
Central Asia is a subregion of Asia that stretches from the Caspian Sea in the southwest and Eastern Europe in the northwest to Western China and Mongolia in the east, and from Afghanistan and Iran in the south to Russia in the north.

The countries as a group are also colloquially referred to as the "-stans" as all have names ending with the Persian suffix "-stan" in both respective native languages and most other languages.

The Huns were a nomadic people who lived in Central Asia, the Caucasus, and Eastern Europe between the 4th and 6th centuries AD. According to European tradition, they were first reported living east of the Volga River, in an area that was part of Scythia at the time. By 370 AD, the Huns had arrived on the Volga, causing the westwards movement of Goths and Alans. By 430, they had established a vast, but short-lived, empire on the Danubian frontier of the Roman empire in Europe. Either under Hunnic hegemony, or fleeing from it, several central and eastern European peoples established kingdoms in the region, including not only Goths and Alans, but also Vandals, Gepids, Heruli, Suebians and Rugians.

The Algonquian languages are a subfamily of the Indigenous languages of the Americas and most of the languages in the Algic language family are included in the group. The name of the Algonquian language family is distinguished from the orthographically similar Algonquin dialect of the Indigenous Ojibwe language (Chippewa), which is a senior member of the Algonquian language family. The term Algonquin has been suggested to derive from the Maliseet word elakómkwik, "they are our relatives/allies".

In the United States, a metropolitan statistical area (MSA) is a geographical region with a relatively high population density at its core and close economic ties throughout the region. Such regions are not legally incorporated as a city or town would be and are not legal administrative divisions like counties or separate entities such as states. As a result, sometimes the precise definition of a given metropolitan area will vary between sources. The statistical criteria for a standard metropolitan area were defined in 1949 and redefined as a metropolitan statistical area in 1983.

The National Football Conference – Northern Division or NFC North is one of the four divisions of the National Football Conference (NFC) in the National Football League (NFL). Nicknamed the "Black and Blue Division" for the rough and tough rivalry games between the teams, it currently has four members: the Chicago Bears, Detroit Lions, Green Bay Packers, and Minnesota Vikings, with the latter three based within most definitions of the Upper Midwest. The NFC North was previously known as the NFC Central from 1970 to 2001. The Tampa Bay Buccaneers were previously members, from 1977, one year after they joined the league as an expansion team, until 2002 when they moved to the NFC South. The division was created in 1967 as the Central Division of the NFL's Western Conference and existed for three seasons before the AFL–NFL merger. After the merger, it was renamed the NFC Central and retained that name until the NFL split into eight divisions in 2002. The four current division teams have been together in the same division or conference since the Vikings joined the league in 1961. The Bears, Lions and Packers have been in the same division or conference since the NFL began a conference format in 1933. Largely because the four teams have played each other at least twice a year, with the exception of the strike-shortened 1982 season, for more than 60 years, the entire division is considered one very large rivalry.

The Central Division is one of the three divisions in the Eastern Conference of the National Basketball Association (NBA). The division consists of five teams, the Chicago Bulls, the Cleveland Cavaliers, the Detroit Pistons, the Indiana Pacers, and the Milwaukee Bucks.
