Algarrobo is a barrio in the municipality of Vega Baja, Puerto Rico. Its population in 2010 was 15,764.[2] [3] [4]
According to the United States Census Bureau, in 2010 the barrio had a total area of square miles, including square miles of land and square miles of water.
Algarrobo was in Spain's gazetteers[5] 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 Algarrobo barrio was 877.[6]
Barrios (which are, in contemporary times, roughly comparable to minor civil divisions)[7] 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 to reparto to barriada to residencial, among others.[8] [9]
