Niagara Falls (/naɪˈæɡrə/ny-AG-ra) is a city in Niagara County, New York, United States. As of the 2010 census, the city had a total population of 50,193, down from the 55,593 recorded in the 2000 census. It is adjacent to the Niagara River, across from the city of Niagara Falls, Ontario, and named after the famed Niagara Falls which they share. The city is within the Buffalo–Niagara Falls Metropolitan Statistical Area as well as the Western New York region.
While the city was formerly occupied by Native Americans, Europeans who migrated to the Niagara Falls in the mid-17th century began to open businesses and develop infrastructure. Later in the 18th and 19th centuries, scientists and businessmen began harnessing the power of the Niagara River for electricity and the city began to attract manufacturers and other businesses that were drawn by the promise of inexpensive hydroelectric power. After the 1960s, however, the city and region witnessed an economic decline consistent with the rest of the Rust Belt as industries left the city and affluent families relocated to nearby suburbs. Globalization has played a large role in the decline of manufacturing in the city.
Despite the decline in heavy industry, Niagara Falls State Park and the downtown area closest to the falls continue to thrive as a result of tourism. The population, however, has continued to decline from a peak of 102,394 in the 1960s due to the loss of manufacturing jobs in the area.
