Like all municipalities of Puerto Rico, Arecibo is subdivided into administrative units called barrios, which are, in contemporary times, roughly comparable to minor civil divisions.
[1] The barrios and subbarrios,[2] in turn, are further subdivided into smaller local populated place areas/units called sectores (sectors in English).
The types of sectores may vary, from normally sector to urbanización[3] to reparto to barriada to residencial, among others.
Some sectors appear in two barrios.
