 The vernacular terminology and 19th century subdivisions for the town is "Bairro" (neighbourhood or quarter).While most of the assigned boundaries match with traditional local designations, some others differ from common traditional use, for instance the northern area of Giesteira is understood as part of Barreiros.This is a result of the City Planning Commission's wish to divide the city with a population of about 3 to 4 thousand in each district.
