At present, due to the development of the new town, the place name Tai Po may refer to Tai Po New Town or the historical area centre Tai Po Market, or the Tai Po District (excluding exclave Sai Kung North) that cover the new town and Lam Tsuen Valley and other area. However, the boundary of Tai Po was not defined. In contrast, a namesake election constituency of Tai Po Market had its legally defined boundary, as well as Tai Po District; Tai Po New Town also had its officially defined boundary in urban planning regulation and law. Moreover, Hong Kong police, as well as primary and secondary schools district, had their own boundaries.
