Guerrero is a rural barrio in the municipality of Aguadilla, Puerto Rico.

[3][4][5] Guerrero was in Spain's gazetteers[6] until Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became an unincorporated territory of the United States.

In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Guerrero barrio was 638.

Barrios (which are, in contemporary times, roughly comparable to minor civil divisions)[16] in turn are further subdivided into smaller local populated place areas/units called sectores (sectors in English).

[17][18][19][20][21] The following sectors are in Guerrero barrio:[22] Comunidad Rafael Hernández, Reparto La Ceiba, Sector La Paloma, Sector Muñiz, Urbanización Jardines Guerrero, and Urbanización Praderas de la Ceiba.
