Throughout its existence the constituency (as can be inferred from its name) included Small Heath ward, but that district was linked with various adjoining parts of the inner-city area of Birmingham.
1950–1955: The County Borough of Birmingham wards of Duddeston, Saltley, and Small Heath.
1955–1974: The County Borough of Birmingham wards of Deritend, Saltley, and Small Heath.
1974–1983: The County Borough of Birmingham wards of Duddeston, Newtown, Saltley, and Small Heath.
Small Heath ward joined a new seat of Birmingham Sparkbrook and Small Heath, while Aston and Nechells wards became part of the redrawn Birmingham Ladywood.
