Neighborhoods in Cleveland refer to the 34 neighborhood communities of the city of Cleveland, Ohio, as defined by the Cleveland City Planning Commission. Based on historical definitions and census data, the neighborhoods serve as the basis for various urban planning initiatives on both the municipal and metropolitan levels. Technically known as Statistical Planning Areas (SPAs), they also provide a "framework for summarizing socio-economic and other statistics within the city." City neighborhood boundaries were last revised by the City Planning Commission in 2012.
