In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Carraízo barrio was 1,159.

Carraízo Dam and Loíza Lake
The Loíza Lake is a reservoir located in Carraizo, formed by the construction of the Carraízo Dam on the Río Grande de Loíza. It serves as the main water supply source of the San Juan metropolitan area.

Popular culture
"Carraízo" is popularly used in Puerto Rican vernacular Spanish as a minced oath to substitute for "carajo" (a vulgar term equivalent to "hell" in Caribbean Spanish). The expression "anda pa'l Carraízo" and its variants is equivalent to "go to heck" or "buzz off" in English. It is considered mild enough to use in polite company. The expression has spread to the Dominican Republic, probably due to the close ties between the two islands.
