A roommate is a person with whom one shares a living facility such as a room or dormitory except when being family or romantically involved. Similar terms include dorm-mate, suite-mate, housemate, or flatmate ("flat": the usual term in British English for an apartment). Flatmate is the term most commonly used in New Zealand, when referring to the rental of an unshared room within any type of dwelling. Another similar term is sharemate (shared living spaces are often called sharehouses in Australia and other Commonwealth countries). A sharehome is a model of household in which a group of usually unrelated people reside together, including lease-by-room arrangements. The term generally applies to people living together in rental properties rather than in properties in which any resident is an owner occupier. In the United Kingdom, the term "roommate" means a person sharing the same bedroom; in the United States and Canada, "roommate" and "housemate" are used interchangeably regardless of whether a bedroom is shared, although at US universities having a roommate commonly implies sharing a bedroom. This article uses the term "roommate" in the US sense of a person one shares a residence with who is not a relative or significant other. The informal term for roommate is roomie, which is commonly used by university students and members of the younger generation.

The most common reason for sharing housing is to reduce the cost of housing. In many rental markets, the monthly rent for a two- or three-bedroom apartment is proportionately less per bedroom than the rent for a one-bedroom apartment (in other words, a three-bedroom flat costs more than a one-bedroom, but not three times as much). By pooling their monthly housing money, a group of people can achieve a lower housing expense at the cost of less privacy. Other motivations are to gain better amenities than those available in single-person housing, to share the work of maintaining a household, and to have the companionship of other people.

Western New York (WNY) is the westernmost region of the U.S. state of New York. The eastern boundary of the region is not consistently defined by state agencies or those who call themselves "Western New Yorkers". Almost all sources agree WNY includes the cities of Buffalo, Niagara Falls, Jamestown, and the surrounding suburbs, as well as the outlying rural areas of Niagara Frontier, and Chautauqua-Alleghany (or the western Southern Tier). Many would also place Rochester and the Genesee Valley in the region, although these locations are also sometimes included in the Finger Lakes Region.

The State of New York sometimes defines the WNY region as including just five counties: Allegany, Cattaraugus, Chautauqua, Erie, and Niagara. The state's Empire State Development Corporation and state health authorities have both mapped the region this way. The state has also used this regional boundary to set policy during the COVID-19 pandemic.

The Niagara Movement (NM) was a civil rights organization founded in 1905 by a group of activists—many of whom were among the vanguard of African-American lawyers in the United States—led by W. E. B. Du Bois and William Monroe Trotter with Mary Burnett Talbert. The Niagara Movement was organized to oppose racial segregation and disenfranchisement. Its members felt the policy of accommodation and conciliation, without voting rights, promoted by Booker T. Washington, was "unmanly." It was named for the "mighty current" of change the group wanted to effect and took Niagara Falls as its symbol. The group did not meet in Niagara Falls, New York, but planned its first conference for nearby Buffalo during the week of July 9, 1905. To avoid a possible racist protest, Du Bois instead hired a small hotel across the border in Fort Erie, Ontario, Canada. The Niagara Movement was the immediate predecessor of the NAACP.

Goat Island (previously called Iris Island) is a small island in the Niagara River, in the middle of Niagara Falls between the Bridal Veil Falls and the Horseshoe Falls. The island is at the southwest corner of the City of Niagara Falls (and of Niagara County), New York, in the United States and is part of Niagara Falls State Park.

Goat Island has no residents but is a destination for tourists visiting the falls on the U.S. side. It has several viewing points, including Terrapin Point. Goat Island is connected to the U.S. mainland by two bridges that carry foot, car, and trackless train traffic, and to the smaller Luna Island (adjacent to the American Falls) by a pedestrian bridge. Goat Island is largely wooded and is interlaced with foot trails. The Cave of the Winds tour elevator provides access down to the foot of the falls.
