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 and the Western New York region . </P> <P> 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 drawn by the promise of inexpensive hydroelectric power . After the 1960s, however, the city and region witnessed an economic decline, following an attempt at urban renewal under then Mayor Lackey . Consistent with the rest of the Rust Belt as industries left the city, old line affluent families relocated to nearby suburbs and out of town . </P>
